A character's cellphone goes off at an inconvenient moment, and the song they use is their ringtone is something they'd be embarrassed by. The Jerk Jock might have the Theme Song from some incredibly geeky television series as his ringtone. The Wicked Cultured villain's ringtone may be a crappy auto-tuned pop song. The Heteronormative Crusader's ringtone may be a song about having Intercourse with You with someone of the same sex. The ringtone of Colonel Badass may be something uncomfortably cute and cheery. The Evil Luddite will be embarrassed to have a ringtone at all. Or one could always just go with a ringtone that anyone would be embarrassed by.
If the character is attempting to be mysterious or intimidating at the time, or attempting to win the trust/approval/respect of someone who find's the song's content objectionable, this is doubly likely to happen. Expect them to answer the phone as quickly as possible just to end the song, and be very grumpy towards the caller.
It isn't always the character's actual phone, but may be instead be a phone belonging to someone else that they're holding onto for some reason. At times it may be a ringtone that wouldn't usually be embarrassing, but the situation makes it inappropriate.
- A beer commercial featured a guy trying to prove to his ex-girlfriend that he's matured enough to hook back up with her ... until his cellphone rings, with "Baby Got Back" as the ringtone. Oops.
- In a T-Mobile myFaves commercial, a guy is asking his friend why his girlfriend is in his "Five" on his phone. His friend tells him he's being paranoid until his phone starts ringing "Secret Lovers" by Atlantic Starr which indicates the guy's girlfriend calling. He promptly takes back his phone.
- Used in Tentai Senshi Sunred. Evil Old Folks Vamp gets this twofold: He picks a dated One-Hit Wonder sung by a Boy Band for his ringtone, making his combat goons point out this makes him look like he's desperately trying (and failing) to be 'modern'. Later, he ends up stuck in Sunred's closet while hiding from Sunred's jerkass colleagues and the cellphone goes off, almost spoiling the hiding place (and making Sunred's colleagues mock what they think is his ringtone).
- In My Hero Academia, All Might's ringtone turns out to be a recording of himself saying "A phonecall is here!" (a play on his Catch-Phrase "I am here!"). His fellow teacher and pro hero Midnight thinks to herself how lame it is.
- In My Cage Norm's secretary Ashley once changed his ringtone to "Barbie Girl". Another time it was shown that Rex's ringtone for his Alpha Bitch girlfriend was "Taps".
- One Nemi strip showed a LARP gathering, which was interrupted by a ringing cellphone. Last panel has the guilty party telling that, worst of all, the ringtone was a Britney Spears song.
- FoxTrot: One strip had Jason swapping out the ringtone on Peter's phone for "I'm a Loser".

- In Easy A, Olive's grandmother sends her a greeting card that plays the Ear Worm song "Pocketful of Sunshine." Olive hates the song initially, then begins to like it, eventually enough to make it her ringtone. When Olive's phone rings later in the film, other people have the same (bad) reaction to hearing the song for the first time.
- In Inside Man, the thieves taking hostages in the bank demand that everyone turn over any cell phones. One executive (read rich white guy) claims he left his phone at home, but the thieves grab the phone of one of the guy's coworkers and dial his number. It rings and loudly plays Kanye West's "Gold Digger". Surprisingly enough for a few seconds the thieves seem like they're going to let the whole thing slide, perhaps out of sheer amusement at the incongruity of the ring tone... then the leader of the group drags the guy off into another room and beats the crap out of him.
- This happens repeatedly to the titular character in Paul Blart: Mall Cop, but only because his phone was lent to him by a teenager.
- In She's the Man, Olivia has Aqua's "Barbie Girl" for her ringtone. This causes some problems when she's impersonating her brother Sebastian and she forgets to change it.
- White House Down: The ring tone on the cell phone of The Mole, who assisted those who took over the White House by becoming Acting President, so he could send them the access codes to launch nuclear missiles to the Middle East, is the main theme of "The Dating Game" (Herb Alpert's "Spanish Flea"). This creates Mood Whiplash during the denouement, where he's exposed to the President of the United States by redialing the terrorist Big Bad's cell phone.

- An early episode of Burn Notice features Michael using a ring tone on his phone as an alarm for when someone sets off a motion sensor he sets up at a safe house for the clients of the week. It's from some flash in the pan girl group.
Teen girl: Nice ring tone.
Michael: It came with the phone.
- In Hannah Montana, season 2 episode 27, "The Test of My Love", when Miley is dating a rich boy and she meets his parents, his parents act rude to her because she's from Tennessee and they see her as a bumpkin. When Miley tries to prove she's sophisticated, her ringtone goes off playing country music which she set to because she felt homesick.
- Completely subverted in House who has a string of seemingly embarrassing ringtones that he uses completely shamelessly. In fact, he appears to have chosen them deliberately to embarrass and mock his team. Calls from chronic adulterer Taub set off "Escape" (The Pina Colada Song).
- Invoked offscreen in the Frasier episode "Taking Liberties". Niles' wife Mel, as part of a domestic conflict, sets his ringtone to "La Cucaracha" before they go to a society funeral.

Unfortunately, he was with Captain Picard who was explaining him some assignment. It looked like the communicators couldn't be turned off, and both Picard and Worf got really annoyed.
- In the Supernatural episode, "The Real Ghostbusters", evil spirit children trapped Sam and Dean along with many patrons at a hotel convention. To get the spirits to free everyone, Sam and Dean recruited an actress to play the ghost of the stern, turn-of-the-century school mistress (who Sam and Dean mistakenly banished earlier) to scare the ghost boys into releasing the hold on the hotel. Everything was going well until the actress' cell phone rang with a jaunty hip-hop tune. Cue her Oh, Crap! moment as the evil spirit children smiled menacingly, realizing she wasn't the school mistress and they had no reason to be scared.
- Oddly averted on the Israeli sitcom Traffic Light: Khefer's ringtone is that of a woman moaning aloud in the throes of passion, but he is never embarrassed about it. Although he does change it to Samantha Fox's "Touch Me", so a moment like this might've taken place offscreen...

- Two and a Half Men: When Jake stays out too long with a girl, her Scary Black Overprotective Dad shows up at Charlie's house. Jake left his cell phone behind, so when Charlie tries to call him, it starts playing a misogynistic rap tune on the coffee table.
- Was the basis of a punishment for Sal in Impractical Jokers. He had to endure multiple calls from the other Jokers during a book reading, and even read a passage from "his" book while the phone rang.
Ringtone: Whose phone is ringing? Mine! Mine! Mine!
- "Weird Al" Yankovic's song "Ringtone" is about this:
Why did I buy the stupid ringtone?
I just can't imagine now
what I was thinking at all!
My friends all stare at me whenever I get a call!
When everybody (everybody)
everybody in the world really hates my ringtone!
- In the Flash series Cactuar and Tonberry by Crazy Boris, Cactuar (actually a criminal identical to Cactuar) busts into a heavily guarded vault to steal the last bottle of A1 steak sauce.

- A minor Running Gag on The Spectacular Spider-Man was Peter's cell phone going off at inconvenient times. One memorable instance had it go off in the middle of Spider-Man's fight with Electro... to the tune of The Itsy Bitsy Spider. It was Peter's designated "Aunt May Alert".
- In Star vs. the Forces of Evil, Marco has his ringtone set to Parry Gripp's "Space Unicorn", which is a real song. "It's supposed to be ironic."
- In Gravity Falls, when Robbie insists that he is over his ex Wendy, his cellphone plays a track sung by him, about "never getting over Wendy." After smashing said phone, he says that it was about a different Wendy.
- Archer subverts it because of course Archer isn't embarrassed by "Mulatto Butts" a song about mixed race buttocks. Not even in front of his mixed race ex-girlfriend. At least one guard also has the same ringtone and also isn't embarrassed about it.
- Hilariously, this happened at UFC fighter Anderson Silva's NSAC hearing over his failed drug test, with one of the panel's ringtone being Salt N Pepa's Let's Talk About Sex. note
