In comics and shows emulating comics, we'll see words which indicate the action taking place. "Bash!" and "Kick!", for example, just happen to sound a bit like the impacts they're describing. They are almost, but not quite Written Sound Effects. Some authors will just bypass the whole "sounds like" thing and use words for the action in loud capital letters. "Glare!" "Leap!" "Flourish!" and even "Idea!"
This is the Unsound Effect. It's a humorous technique, although it is also seen in fight scenes ("Block!" "Slash!").
This is usually attributed to Richie Rich in the original Harvey Comics versions, which lasted from the 1950s to the 1980s. They included such effects as "BOUNCE!" for large rubber balls impacting a hard surface, and went on to "EXPAND!" when Richie utilized one of Prof. Keenbean's Applied Phlebotinum devices meant to go from pocket-size miniature tool/vehicle/etc. to full-size.
It's worth noting that manga has different but similar conventions regarding onomatopoeia. Manga has much more than can be done with an Unsound Effect. Japanese writers will use sound effects to denote sounds, like heartbeats or door slams, but also to represent more abstract events like "smiling" ("niko niko"), "sudden realization" ("ha"), "the sound of silence" ("shiiiiiiin"), "the sound of staring" ("jiiiiiiiiii") or even "the sound of blushing" ("kaaaaa"). These are known as phenomimes when they describe external phenomena and psychomimes when they describe psychological states (both can be referred to in Japanese as gitaigo, lit. "mimetic words", since they mimetize such cases). Some anime, generally the more surreal sort, turn these into actual sound effects.
And sometimes, the unsound effect isn't even written. A Super-Deformed version of the character in the margin, a mascot, an animal, or other living thing in the background will say or represent the character's feelings.
Related to Editorial Synaesthesia. See also Visible Silence, the Unsound Effect for no sound; and Sound Defect for real sounds that go wrong. When this occurs in-universe it's Saying Sound Effects Out Loud.

It is common practice for closed captioning to caption sound effects as well. There is a Windex ad in which the mother cleans a window with Windex to let the sun shine in and wake up her kids. The kids rush out while the mother smirks — because it's Saturday. Her smirk is captioned as "(mother smirks)".
Why would you even need to caption that? You can see it.
In One Piece Chimney did her own sound effect for staring (jiiiiiii).note "Jii..." is for some reason the Japanese onomatopoeia for staring.
In this page during the Alabasta arc, the camel in the last panel gets, appropriately, CAMEL!!
When Zoro battles with Kaku in Enies Lobby, he is so underwhelmed and shocked by the lameness of Kaku's semi-human form he says "You look like sh*t!" To which Kaku says "GABEEN!!"note "Gabeen" is the Japanese onomatopoeia for a jaw-drop or similar shocked reaction.
The "Kaa" onomatopoeia is seldom used for a blinding sunlight in manga. The same sound effect is also used for Luminescent Blushes.
The Mahou Sensei Negima! manga does this a lot. Of course, this is probably due to the translators being very faithful to the original; during a silent scene you'll see the giant "shiiiin" kana with tiny English "the sound of silence" written underneath.
There's also a rather humorous "Pettanko" sound effect when Anya first sees Yue and Nodoka.
When Negi goes all out the Kanji for "Destruction" appears when he hits someone.
Russia does this too in one episode of the anime of Axis Powers Hetalia - as in, he actually says "jiiiiiii..." while staring at someone. A second later, he does it again, only louder. The other character looks severely uncomfortable by this point.
The manga MPD Psycho employs this trope in both humorous and straight forms, for instance, when Amamiya's glasses gleam with light, the other characters swear they can hear the "shing" noise that results. An example of the serious form of the trope in action is the "dokun" or "kadoom" noise that indicates Amamiya's personality changing.
A burn victim in Detective Conan had a speech balloon reading "mouthing words" or something to that effect, having been too injured to say anything discernible.
In Dr. Slump, Genki Girl Arale's greetings are so loud and boisterous that the sound effect for it ("KON'CHWA!" - more often contracted to "N'CHA!" - , approximately, due to a Verbal Tic) easily dwarfs her and knocks the people she greets off their feet. The aliens attempt to weaponize this power, but fail every time.
Baby Steps: After his first grueling day of tennis training, protagonist E-chan's inability to stand up from his desk was denoted by "shivering" sound effects.
The Ranma ½ manga is lousy with the "Boot" onomatopoeia for whenever someone gets punted into the sky by a Megaton Kick. Ironically enough, NONE of the characters in the series, with the exception of Ryoga, ever wear boots.
We also got LOOOOOOOOM for bad guys looking Badass followed by a much smaller LOOOOM for the good guys trying to but not managing it.
By the fourth episode of Panty & Stocking with Garterbelt, the sound effects have branched out into unusual territory. "Nice Dunk!", "Muffin Top", and "Red Carpet" (yeah...) are just a few examples.
A crowning example occurs in Episode 11: Panty is channel-surfing, and while we can't see the TV, we can see the Written Sound Effects that each channel produces. The first channel goes "Blah Blah Blah," the second channel goes "Yak Yak Yak," and the third channel (clearly porn by the sound) goes "A Cock Sucker."
During an undersea episode early in the Keroro Gunsou anime, Keroro's platoon accidentally fire several torpedos at a city on the bottom of the sea. He hopes they all miss, but...they all hit. All of them. Direct hits too. The platoon's reaction can only be described as "Atmosphere of Oh Shit".
In one chapter of the manga, Kululu decides to shake his team-mates out of a streak of complacency by brain-washing their friends and forcing them to fight. Fuyuki offers to face Keroro in a riddle contest instead, to which Keroro responds "Alright, but I should warn you, Master Fuyuki, I filibuster all riddles!" As the other members of the Keroro Platoon do battle, you can see little word balloons with the words "Riddle!" and "Filibuster!" in the background.
At least one scanlator translated the sound made by Tobi teleporting to some place as "appear".'
Deidara's explosions are always preceded by Yeeaagh! in the English manga. This lends itself to a Woolseyism when some of his bombs land near Tobi:
Tobi: Time out, partner! Don't Yeeaagh yet!
Kenichi: The Mightiest Disciple once had Kenichi outlining to a bunch of delinquents exactly why being a delinquent was a bad lifestyle choice, punctuated with the words "SOUND ARGUMENT!" dramatically appearing at the end of his speech.
In X-Men, at least one X-Babies encounter ("Mojo Mayhem") has gone this way (with arguing murmurs written as "argue" or "debate" or "mutter" and the like.)
Chris Claremont (as noted above, since he wrote the X-Babies storyline) tended to use this device, especially toward the end of his stint on Uncanny X-Men. In one issue we see an angry mob in the distance, and as they approach their angry murmuring is expressed as unsounds expressing their intent to do horrible things to the object of their wrath, such as "murder," "mutilate," "bludgeon", and "sue."
In one issue by Claremont, Jubilee is served some Foreign Queasine and reacts with "That's it, that's it, that's IT!", followed by a speech bubble simply saying "hate, scream, cry, rage, rant, gripe, shriek!"
Averted in an issue of the Thor comic book, where the Hulk hits Thor with an entire freight train (complete with attached cars). The editor's note on the page confesses that there's no onomatopoeia there because nothing they could think of would do the scene justice.
The same thing happened when the Thing punched Sandman into his component particles while both were underwater.
MAD, illustrating the reality of a six-man utility crew - one guy digging a hole (accompanied by the sound effect "dig") while the other five are in various states of leisure (accompanied by "eat", "siiiip", "snooze", "hang out", and "read").
Another comic features a massive five-way collision accompanied by "HORRENDOUS UNSPELLABLE SOUND EFFECT!"
Wally Wood once told a detective story entirely in pictures and exaggerated sound effects (with a couple of unsounds). All the murder victims produced the same sequence of AAAARGH!..THUD...BOUNCE BOUNCE and, in the first case the guy who had been shot rounded off with a quiet BLEED BLEED. The detective was quite mystified by the screams until he realized that the killer was one Joe Aaaargh, alias Joe Eeeech, alias Joe Uuuuugh.
The Don Martin strips were famous for featuring bizarre sound effects like "wugga wugga!", "zit, zit, swizap!" or simply "fump!".
The New Yorker had a cartoon by Roz Chast called "No Action Comics." It had sound effects like "MULL! MULL!" and "WORRY! WORRY!"
Frequently used in Twisted Toyfare Theatre. Examples include Spider-Man running across some assorted Beanie Baby animals. Some go "moo moo", some go "oink oink" and some go "kangaroo sound kangaroo sound". And when he gets them to stampede, it's "angry moo, angry moo" and "angry kangaroo sound, angry kangaroo sound".
A much, much later strip features Christian Bale interrupting the Manly Men of Action's dancing with the sound effect of "record screeching to a halt!" Dolph Lundgren then displays his musical talent by playing a drum solo; the sound effect is "Drum Solo!"
German comic artist Ralf König is good at this. he rather describes the mood of scenes with his unsounds. One scene shows a guy laying in bed, hearing "sounds" like "cooking coffee" and "doorclap".
The Tick is also fond of this, with the best being "CONTEMPLATE!"
In the first issue, The Tick and Clark Oppenheimer are fighting in a subway tunnel, when a train hits them, making the following noises: *BANG* *CRASH* *REALLY LOUD NOISE!*
At one point the Tick disarms the Red Scare of his hammer and sickle with "Take!" sound effects.
Amerimanga Ninja High School has used literal sound effects from the beginning of its run. They do sort of mirror manga's onomonepetic effects, but Ben Dunn has admitted he got the idea from Richie Rich.
One example: a character lifts a huge tree out of the ground, to the sound of *UPROOT*
The Time Traveling schoolteacher whisks a cloth away from her time machine: REVEAL! Also, two girls ponder a question with the effects: THINK THINK THINK THINK.
De Familie Fortuin, a Dutch comic about the titular white trash family, has used such sound effects as *ENORMOUS EXPLOSION! FLYING BODY PARTS! BLEEDING GUMS! COOL MAN!* and *EXPLODING SCHOOL WITH EVERYONE INSIDE*.
Dinosaurs for Hire featured Archie the T.rex dusting himself off ("dust, dust") and Reese the Stegosaurus adjusting his eyepatch ("adjust").
Another Dutch comic, De Generaal had one when the eponymous general is dropped with tank and all from a hot air balloon (don't ask): *SMASH OF GIGANTIC PROPORTIONS!*
A series of Disney albums had Goofy playing different historical persons. In the Beethoven story all sound words were composer names. Knocking on a door sounded like BACH BACH, knocking over a pile of stuff produced a loud BRAHMS and so on.
Unsound effects were used a lot in Erika Fuchs's German Disney translations (one of her more creative ones was where "censored" was replaced by "Einziger Aufschrei der erregten Massen" (single outcry of the excited masses"). German-speakers brought up on Fuchs' Donald Duck comics will sometimes use such unsound effects like "grübel, grübel" (ponder, ponder), and at conventions of the D. O. N. A. L. D. (Deutsche Organisation Nichtkommerzieller Anhänger des lauteren Donaldismus = German Organisation of Non-Commercial Adherents of Pure Donaldism) they customarily applaud by chanting "klatsch, klatsch, klatsch!" (clap, clap, clap!).
BOWL! (Note that it's not the sound of bowling; it's the sound of some guy going to a bowling alley. Yeah.) Also, DREAM! MAGIC!
The Incredible Hercules no longer even tries to have standard sound effects. Instead, the sound of an impressive punch to the face is WHATAMANNN, a dragon's firebreath goes SMAAAAAAAAAUG and an attack aimed squarely at the opponent's nipples is represented with a bright purple NURP.
Arguably the best sound effect ever: Hercules smashing a wall while impersonating Thor: GODDATHUNDAA!
Hercules punching Thor in the face in mid-sentence: SUKKAPUNCH!
The sequel miniseries, Prince of Power, carries on the grand tradition with getting chucked into a table being IKKKEA!, among others.
Archie's Sonic the Hedgehog comics had unsound effects in the early days before they went down the toilet. Two that stand out are "RABOOM" and "ROBOOMNIK". Guess who was getting blown up on those occasions.
Scott Pilgrim has a number of these, including "GLARE", "FLING", the rather puffy and cute "POUT", and "BOSS FIGHT."
In The Life and Times of Scrooge McDuck, "The Cowboy Captain of the Cutty Sark", our intrepid hero experiences the Krakatoa explosion firsthand (he did, however, stuff his ears full of cotton, which somehow worked). We are treated to a beautiful rendition of the explosion, but the sound-bubble only contains an asterisk. A note from the editor points out:
In consideration of the fact that on August 27, 1883, the island of Krakatoa exploded with a force equivalent to 10,000 hydrogen bombs and produced the loudest noise in history, we deemed it wise to delete the sound effect to preserve the sanity (and ears) of our readers.
The Wallace & Gromit comic Anoraknophobia had sound effects including "LOUD CLICK" and "DEEP GLOOM AND CONCERN".
Pure example: In an old Harvey Comic, a character gets a plunger to the face with a "BWOP!" sound effect - he pulls it off with an "UNBWOP!" sound effect.
A fight scene between the Mane Six and some changelings in issue 1 of IDW's My Little Pony Friendship Is Magic comic features Rainbow Dash following up a "KICK" with a "BETTER KICK!"
Subtitles for the hearing impaired can come off a bit like this when done badly. There's no better mood killer in the middle of a romantic moment than seeing *dramatic music intensifies* pop up on screen.
In Blazing Saddles, this is lampshaded during a meeting with the governor. After it's announced that Rock Ridge had been bombed, the Governor shouts "We must do something about this immediately! Immediately! Immediately! Harumph! Harumph! Harumph!" Everyone else says Harumph along with him, with one notable exception. "I didn't get a 'harumph' out of that guy."
Gaspode, a talking dog says 'woof'. Due to a near-universal Weirdness Censor, this mostly just makes people look at him funny.
And there's a recurring theme in Discworld of words for the sounds that things would make if they did make a sound except that they don't. These are usually associated with reflected light, and for some reason usually begin with "gl." "Glint," "gleam," and "glisten" are given as examples.
Live Action TV
The "Bicycle Repairman" sketch from Monty Python's Flying Circus has intertitle cards with effects like: "Screw!", "Bend!", "Inflate!", and "Alter Saddle!"
The 1960s Batman TV series had sound effects in every fight scene, and always slipped a few unsounds in as well (e.g. "Sock!" or "Ouch!").
The Monkees parody this in one episode with a fight that has words like Rumble! Plink! Plank! Plunk! Miss! Foo! Bing! Bong! Bang! Splat! Kretch! Plop! Splinter! on the screen. (At the word Kretch, Peter Tork stops fighting, looks into the camera, and says, "Kretch???" before they agree to stop fighting and start breaking furniture.)
The Avengers also parodies this in "The Winged Avenger". At the end of the episode, Steed fights the villain by hitting him with poster-sized mockups of comic book panels, each containing a word like "Pow!" and "Splat!" Meanwhile, "Batman"-like music is playing in the background.
When a piece of viewer mail on Attack of the Show! asked what kind of sound effect they would want to have if they were in a comic, Kevin Pereira admitted he would want the word "SKANK!" to pop up when he slapped someone in the face.
The Muppet Show did a sketch entirely in action and spoken sound/unsound words. It started with a creature (possibly played by Animal) trudging through the wilderness while muttering "trudge trudge trudge" until it got interrupted by something flying past with a loud "FLY! FLY!" which made it stop and go "ponder... ponder... ponder..." as it, well, pondered the strange event. After this had happened a couple of times the wanderer lost its patience and went "fret foam" as it picked up a heavy stick, and the next time the flyer passed it got stopped by a massive SMASH SMASH!
On The Tonight Show, Conan O'Brien visits a Foley stage and makes his own sound effects, including a shout of "Throw baby!" when a character throws a baby.
During one game of "Props", Wayne had to somehow mime being a lamp that was turned on. So he just simply said "ON!" loudly.
PDQ Bach's Good King Kong Looked Out has a choir singing an Unsound Effect - "hear", in this case - because seriously, what onomatopoeia could possibly used?
In Stan Freberg Presents The United States of America, Christopher Columbus' crew indicate their displeasure with a chant of "rumble rumble rumble, mutiny mutiny mutiny". This has achieved a Memetic Mutation status, and Tyne Daly mentioning the phrase to Freberg got her a role in the sequel to the program.
On the Who song "A Quick One While He's Away," the band had originally planned to have a cello accompaniment in one section. But the money ran out, so the band just sang "cello cello cello cello" in the background over and over.
One Bloom County featured the wonderfully memorable "unprovokedKICK!"
A Calvin And Hobbes strip has Calvin walking around in galoshes that go "galosh galosh galosh".
In a school strip, Susie asks Calvin to name the old capital of Poland, and hears him mutter, "KRAKOW! KRAKOW!" which happens to be the right answer but is really a sound effect from his Imagine Spot about Spaceman Spiff fighting aliens.
Yet another involves Calvin asking Hobbes to go spelunking. When Hobbes points out that there are no caves nearby, Calvin takes him to a lake and they proceed to drop rocks into the water... which make a "spelunk" sound effect.
Dick Tracy has had some very strange sound effects such as "sqlud" for Dick getting hit in the face, "qwink" for a machine powering down, and "qlunq" for a briefcase hitting Dick in the head.
For Better or for Worse is in love with this trope—partly because every other Sunday strip is mostly silent, save for the Unsound Effects flying all over the place. One panel where the family dog was eating something was accompanied by *gobble snarf eat*.
Another, dealing with Elly's frustrations with a fax/copier, had UNPLUG, although the design of the balloon made it ambiguous whether that was a sound effect or Elly loudly vocalizing the action as a form of venting.
One FoxTrot strip used *crank crank crank* and *uncrank uncrank uncrank* for the sound of someone turning up, then turning down, a thermostat.
There is a Garfield comic where Garfield is unscrewing a saltshaker with the sound effect *unscrew* hanging in midair. It's unclear how that sounds any different from just plain ol' screwing.
In an early (1950s-era) Peanuts strip, Charlie Brown is perplexed when Lucy tosses a pebble into a pond with a "ker-SPLASH!", and Linus jumps into a pile of leaves with a "ker-LEAF!".
There was also one about how Snoopy doesn't like to be scratched on the head; he prefers to be "skritched." Sure enough, when Schroeder works his fingers on Snoopy's head, the sound is "Skritch skritch skritch."
Another strip has Linus telling Charlie Brown that it's "soppping wet" outside. Charlie Brown remarks "I think you mean sopping wet", followed by Snoopy walking in accompanied by sound effects of "SOPPP SOPPP SOPPP".
In yet another strip, one of Snoopy's bird friends goes, "Gripe gripe gripe, complain complain complain, crab crab crab," after which Snoopy wonders, "If he doesn't like it, why does he go there every year?"
Pens in the Pearls Before Swine world make "write write write" and "scribble scribble scribble" sounds when used. The creator, Stefan Pastis, admits to this bit of creative license in the book commentaries.
At least in the early days of the strip, there would also be "sound" effects such as "run run run run" and "hurl!"
The Wizard of Id is fond of this trope, using such sound effects as "Deliberate deliberate deliberate" for a jury.
Or (from the underground press) "Print print print".
A Zits strip showed Jeremy taking a test, with the Unsound Effect "Essay! Essay! Essay! Essay! Essay!"
At one point he was also seen using a computer, with the UE "double-click"
In Pokémon HeartGold and SoulSilver, you have to help a Kimono Girl whose sandals are frozen to the ground in the Ice Cave. You do this by shoving her. The sound effect shown in the text box for this? "Shove!"
Nanaca Crash has "DEATH?" when you hit one of the guys, as well as "SLOW DOWN" and "STOP!" and others, though those might just be describing what happened to you rather than being actual sound effects.
The instruction manual for the PS2 game Flower, Sun and Rain includes screenshots accompanied by ordinary sound effect words, until one image gets the effect "KATHARINE!"
Final Fantasy VI—Eating food on the Phantom train results in the following message in a text box: "*gobble* *snarf* *snap* HP/MP restored, and status ailments like Poison cured!"
In battle, attacks that miss also result in the word "MISS" appearing over the character.
Any Valve game since Half-Life 2 has this in the closed captions. Includes things like "*pain!*", "*laughter*", "[Crowbar Thwap!]", "[Bullet—Near Miss!]", "[Engine starting in water]", "[Headcrab Burning]", and of course, "[Beep-beep-beeeeeeeeep.] User Fatality.". Portal brings us "Weeeeeeeeeeeeeeeeeeeeee[bzzt]", "[Peppy Music]" and "[Calming Wind]".
A cheat in Age Of Empires III, in reference to Teen Girl Squad (see just below), causes an effect that when a unit dies, the name of its killer pops up above it, followed by "-ed". So units can get "Musketeer'ed!", "Imperial Rocket'ed!", or, in one campaign level, "Fixed Gun Ruins'ed!".
One segment from AMV Hell 4 involved a Paranoia Agent / Batman mash-up. In it, Shonen Bat/Lil' Slugger is beating down people with his bat, while the typical Written Sound Effect staples seen in Adam West's Batman. The last one of the bunch (it's very briefly seen; you have to be quick to catch it) is OMGWTF!. The clip was titled "Shonen Batman".
The Ogres on Unforgotten Realms frequently mutter the words "Ogre Sounds" to no one in particular.
Yahtzee does this occasionally in his Zero Punctuation reviews. One notable example showed someone rotoscoping images by sitting at a computer that made the sound, "Rotoscope rotoscope."
Before we start, let us warn you: this section is particularly long. For some reason, webcomics are a very fertile terrain for the Unsound Effect.
Erfworld, as pictured above. Also includes sound effects like "Warn", "Sweep", or even "redox". Interestingly, it avoids this trope more often than not, sometimes confusing readers as to what the sound effect represents. For example, some were unsure what "free-deep" was, until it was explained that it was a cricket chirp.
Some of the comic's pop-culture references are written into sound effects (e.g. "NWOBHM" — New Wave Of British Heavy Metal).
The joke of the PLOT effect is, of course, that it is also representing the sound of what's happening.
User Friendly had some 'interesting' sounds for coffee brewing: "sizzle", "congeal", "fold proteins", "curdle", "sprout". Of course, given that previous coffee-brewing efforts have intentionally created a brew that has the properties of Xenomorph acid-for-blood and one that was made with parts of Hastur, this may indicate a success.
In another strip, when someone was writing a program to trick someone else, the Unsounds were 'Code Plot Plan' as he was typing.
The Adventures of Dr. McNinja: Dr McN jumps on a motorbike driven by a ninja and whispers something in his ear to creep him out and throw him off the bike. The resulting sound effect is "CREEPED OUT ENOUGH TO BE THROWN EASILY FROM THE BIKE". This is then Lampshaded in the Alt Text which reads "Oh come on. That is not a real sound effect at all."
Played with left to right and back to front here.WHCRUNCHnote Weird that the motorcycle guy landed right where Doc had painted WHCRUNCH in his parking lot. Because that's probably exactly what it sounded like.
MAGIC! Followed by the Alt Text admission "I uh... I couldn't figure out a sound effect."
The Wotch and its spinoff Cheer! do this heavily, with examples such as: *Ka-girl* *open*, *swap*, *stare*, *harm*, *regress*, *swap*, *gravity*, *vertical ascent*, *tie up*, *disguise*, *not there*, *...psyche* , and many more. Yes, with the asterisks.
Both series use them to the point that an actual sound effect in either goes on to become pretty rare, and there's a running gag of "ka-something" sounds. "Ka-zap" eventually becomes "Ka-*effect here* " which is how "ka-girl" got started (and eventually became a verb. "Why am I always the one you ka-girl for a joke?") Eventually, you have stuff like "Ka-annoyed!" after too many transformations, and "Ka-meraderie!" when 32 tries to gloss over the fact that nobody believes she's the person she's standing in for by acting all chummy. The best is "ka-asking-for-it!"
In one guest comic Jacques drew, the characters of Niego walk into Coffee of Doom and are promptly assaulted by Raven with a chair, with the Unsound Effect of "CHAIR!" and "CHAIR AGAIN!" as they're beat upon.
The "chief" character's warning came too late, it seems, as someone already made a move and got trashcanned, while the "vixen" is now blowing a bubble of chewing gum. The rest of the comic goes directly into "I Am Not Making This Up" territory (and in several places, makes me wish for some kind of mind/eye bleach).
This cartoon from deviantART utilizes a lot of unsound effects, like *drink*, *belch*, *incredible loud belch*, and *crickets chirp*. Strangely, it also includes the best onomatopoeia for a power belch ever seen.
Strip 12 of OMFE averts another trope by having an orbital cannon fire with a mighty "NOSOUNDINSPACE"
In an early strip, Belkar says he could probably sunder Elan's sword just by talking too loudly. Shortly after, they get spotted by a chimera, and Belkar exclaims "DAMN IT!", and Elan's rapier breaks in two, the sound effect being written as "sunder".
Geist Panik is absolutely in love with this trope. Notable examples include "Ka-Evil!", "SPAS-12", and, in one case where even the author appeared at a loss, "Um... Fish Noises?" Brian Wilson, the author, has stated that he struggles with coming up with sound effect noises and eventually decided to simply write what was happening.
And even more recently, "Hoping! ... Real Hard!!" along with "Ominous!" as the Knob squeezes a juice-box.
There's also "Bush Hat!" "Shadow!" and "Steve Says Hello!". By the way, Steve is a plant.
Steve is taken even further, his sound effect being "Omghax!", then "Steve accepts!"
The strip recently coined the word "Ninj!" as the official Sound of Silence, representing the silence produced by a ninja. So, an exploding spaceship can now have the sound effect "NINJ!" in big block letters.
The defunct Sprite Comic194X had a strip wherein a character hits several people with his "Volunteerin' Stick," making sound effects such as "PERSUADE!" (194X's archive doesn't allow direct links to comics; this happens in #70.)
ThisTale of the Cave strip features insults hidden in the miss sound effects. Naturally, the protagonist shoots the sound effect guy. This is the only shot he has successfully made to date.
Mac Hall had one strip where a human character in The Matrix universe who points out the film's plotholes is blasted by a laser gun, which makes the sound *VOIP!*. Not really an Unsound Effect...until one sees the strip immediately after, where one of the machines points out a plothole, and is blasted by a *VERY ADVANCED VOIP!*
"Glitch" and "chakat" are proper sound effects, positively visceral and metallic, respectively. Anyhow, overall the unsound effects in Sluggy Freelance vary on a scale between humorous and action-explicating; these often overlap, such as in "stabbity stabbity STAB" being used for three consecutive attempts at stabbing the same target that keeps moving out of the way. Of course, the line to sound effects isn't entirely straightforward either.
Not So Distant uses this quite a bit. Amusingly, "stab" was not used when the main character was stabbed in the leg (splorch), but it WAS used earlier when a pillow got stuck to one of his head spikes (preceded by "flop" as he flopped onto his bed).
Lucy Knisley makes good use of this one, particularly in "Some Thumb Sucking", in which she uses 'stress stress stress', 'calm', 'suspicion' and 'sneaky' (not to mention the variant 'sneeeaky' and then some more 'calm') as sound effects in only 9 panels.
Used and abused by Chicanery, with such sterling examples as "*spork*", "STEVE!", and "Brain refusing to function noises".
Homestuck: "Egg!"Lampshaded (uh, sort of) a little later, when the Peregrine Mendicant hears "EGG" and comments that "it almost sounded like a huge egg appeared in the sky and landed, and then someone mysterious teleported out of it."
In Scandinavia and the World, Finland doesn't really talk much so there is a lot of this trope around him like. "VIHTA!!!" "SNOW!!!" "WEAK PROTEST!!!" and "crocodile tears to get ice cream." There are also non-Finland-related ones like "kiss of beer."
Unsound Effects are practically a Running Gag at this point; they show up in nearly every episode.
The words written on the "Poof" clouds when Cosmo and Wanda (actually any magic-using character, actually) does something with magic are usually related to a wish or another event. Norm the Genie, on the other hand, only has "GONG!". The Pixies have "PING!", as well. Unsound effects show up a great deal in the Crimson Chin comics, which of course are parodies of normal superhero comics, which love this trope.
The best comes from the opening cutscene of a videogame, where Cosmo summons up Da Rules with the "Poof" cloud "PLOT DEVICE!"
Appearances by Mermaid Man and Barnacle Boy on Sponge Bob Square Pants often use these as part of their being a Batman spoof: "HANG UP!" "SIT!" "WINK!"
KING ME! when the characters were playing checkers.
Not to mention the production values of their old show: PROP! CARDBOARD! LAME!
The Looney Tunes short "Now Hear This" climaxes with a gigantic explosion, accompanied by the words "GIGANTIC EXPLOSION" appearing onscreen, probably one of the most unimaginative onomatopoeia ever devised.
In the My Little Pony: Friendship Is Magic episode "Party of One", Applejack and her friends are up to something in the barn at Sweet Apple Acres, and keeping it a secret from Pinkie Pie. Applejack tells a skeptical Pinkie that they're doing renovations, and has the other girls make construction noises in the background... which includes Twilight Sparkle shouting "Safety gear!" and Rainbow Dash saying "Drill, drill!"
The "Good Manners with Max" shorts on the old Playhouse Disney block always began like this:
Max: Hi, my name is Max, and this is my dog Banjo. Say hi, Banjo.
