Ninja Sex Party is a New York-based comedy duo consisting of Danny Sexbang (Dan Avidan) and Ninja Brian (Brian Wecht). To date, the band has two albums out: NSFW (2011) and Strawberries and Cream (2013). Their next album, Attitude City, is forthcoming.Their channel can be viewed here. Also at the moment, Danny is now part of the Game Grumps with Egoraptor, and is also part of its sister show Steam Train. The band also collaborated with Egoraptor for Starbomb.
Anachronism Stew: Quite a lot of this in Dinosaur Laser Fight, where they fight with lasers, in space (which was invented by Albert Einstein), with robots and sharks.
Arson, Murder, and Jaywalking: Rhinoceratops and Superpuma caused a lot of collateral damage, including pissing on Cuba, killing a million people... and stepping on Dan's lawn and scratching his car.
Artistic License - Music: Danny's signature instrument is a blue electric guitar... or at least it's played as one. It's actually a bass.
Most notably in the Manticore video, where Danny inexplicably plays a face-meltingly awesome guitar solo on the bass.
Danny mentions it as a blue bass in Rhinoceratops Vs. Superpuma, though the previous instances of it being used as a guitar remain unexplained.
Ass Kicks You: The legendary Manticore will "Kick your ass in with his feet, and then kick your feet with his gigantic ass". Although in the video all he does during this line is stick some fried eggs in his pants and flex his crotch until they come out scrambled.
During the Ninja Sex Party/Steam Train panel at MAG Fest 2014, Danny and Brian (out of character) confirmed that Brian really did eat the pepper rather than keeping it in his mask (as some had suspected) and that the lack of blinking was real and not a post-production edit. Apparently everybody present was way more impressed at how long he went without blinking than they were that he ate the pepper.
Bullying a Dragon: Danny seems to take great enjoyment from insulting Ninja Brian during their songs, NSP Theme, If We Were Gay and The Decision being the most notable examples of this. You'd have thought that he would have learnt better not to mock the murderous ninja guy (Brian's retribution is always swift and deadly, though not usually permanent).
But Not Too Gay: If We Were Gay is a speculative song about what the world would be like if the duo was gay. However, Danny's quick to assure us that if they were, it'd be mostly Brian.
But Thou Must: In FYI I wanna F your A, on the PTAnote Penis Touching Association application, the three choices are "Yes", "Hell Yes", and "I Already Am".
Butt Monkey: Barry has been beaten up or murdered just as often as Danny, sometimes even by Danny.
Breaking the Fourth Wall: Brian's been known to do this, such as the end of their video for The Ultimate Sandwich, where he is shown to read the on-screen subtitles while Danny speaks in Spanish.
Call Back: So much in Dragon Slayer, like the animal costumes from the Starbomb previews, Danny's "Stuff that Totally Happened" book is written by Mike Aruba, and the return of the Manticore.
Sometimes played straight, like in Sex Training where he steals a guy's girlfriend, Rhinoceratops vs. Superpuma where he talks about getting laid twice in a row, and I Just Want To (Dance) where he talks about banging a thousand hotter girls than the hottest girl you've ever seen, etc.
Comedic Sociopath: Ninja Brian. He's either killing someone, or thinking about killing someone. Usually someone nearby. Usually Danny. Best Friends Forever directly addresses this and how big of a problem it is for Danny, since Brian ends up killing all his friends (and then him).
Commitment Issues: The reason Danny goes on his road trip in the titular song is because he's going out with a girl he actually likes and could see himself settling down with, so he decides to journey across America and bang as many girls as possible to get the commitment out of his system.
Out of character, Danny himself has admitted to this.
Early-Installment Weirdness: The first music video, "I Just Want To (Dance)". It's not as overtly sexual in subject matter as future songs would become, with Danny even implying he's not interested in romance anymore, and most notably, Ninja Brian is unmasked and singing at one point. Just as well, Danny states that prior to becoming Danny Sexbang, he'd been "the toughest fucking ninja that you've ever seen", even saying this to Ninja Brian, who doesn't seem to object, implying that this is true. This is later proven wrong so so so many times.
Epic Fail: In the song Dragon Slayer, Danny Sexbang is chatting up a girl at a party, and trying to get her to go out with him by telling ridiculous tales about himself (like, say, that he slew a dragon). How does this work out for him?
Evil Counterpart: According to Danny, NSP has a rival group called Samurai Abstinence Patrol. They'll be featured in Attitude City.
Foreshadowing: In the aforementioned Let's Get This Terrible Party Started video, there is artwork of Danny, Brian, and Egoraptor in futuristic Tron-esque suits, foreshadowing Starbomb, a collaborative album between Arin and the band.
In The Ultimate Sandwich video, before the actual song begins, the background music is the same that was used for the Starbomb song, The Simple Plot of Final Fantasy VII.
Danny has mentioned on a few occasions that Ninja Sex Party have a rival gang named Samurai Abstinence Patrol. They'll be appearing in the band's next album.
In "The Second NSP Album Is Here!" the music playing is actually the music for Starbomb's "Mega Marital Problems".
Lovecraft Lite: Rhinoceratops vs Superpuma starts out with the two titular monsters threatening the earth in their "massive-ass brawl", but The Power of Rock saves the day... by influencing them to have sex with each other. Lovecraft doesn't get Liter than this.
Major Injury Underreaction: Many, many examples, usually involving Brian killing Danny in some fashion. The best example comes in If We Were Gay, when Danny just says "ow" and "ouch" repeatedly in a Dull Surprise manner as he falls down the cliff.
Matzo Fever: Danny at least thinks of himself this way, being a Jewish lover. He does however have his share of turnoffs for comedic effect.
Danny Sexbang is a self-important douchebag who constantly lies about his achievements and thinks he's more attractive than he actually is, while acting incredibly sexist and disrespectful to every girl he hits on. In real life, Dan Avidan is incredibly chilled, very humble, and has a large following of fangirls (and boys).
Ninja Brian is a murderous psycho. In real life, Brian Wecht is a theoretical physicist, comedian, and pianist, and is a really cool guy with a good sense of humor.
Memetic Badass: Invoked with the Manticore, which literally invented death and all things that are bad.
Also invoked with Ninja Brian in general, since he has killed several people, including The Slender Man.
Ninja Pirate Zombie Robot: In the band name, as well as quite a bit of their music. Unicorn Wizard is basically this trope in song form.
Serial Escalation / Recycled INSPACE: Road Trip starts off as just a trip around America to have sex with as many girls as possible. It eventually escalates into a world tour before Danny decides the only way to top that is to go into space and bang hot alien chicks.
Smarter Than You Look: Both Danny and Brian are way smarter than they make themselves out to seem. Extremely with Brian who's a frigging theoretical physicist.
Space Is Noisy: Averted and discussed in Dinosaur Laser Fight: "But it was quiet because in space there is no sound".
Special Effects Failure: Invoked as part of the band's visual style in their music videos. It's done intentionally cheap, with d-grade costumes and props, and blatant, obvious use of green screen. They even use MS paint drawings on occasion for diagrams.
Speed Sex: Parodied in Three Minutes of Ecstasy. Danny doesn't see it as a problem, and in fact makes it out like anything more would be too much of a good thing.
Suspiciously Specific Denial: In part 1 of the Sacred Chalice, Danny backpedals after saying he hired a hooker to join the party, saying it was another robot and definitely not a hooker.
The dragon in Dragon Slayer is definitely a dragon and not some guy Dan met at the bus station in a dragon suit. (And if it was, that guy certainly wouldn't be Egoraptor, either.)
Take That: When listing the things that Brian likes to suck (dicks), one of the images that flashes by is Mel Gibson. As stated on Game Grumps, Danny himself has a strong personal hatred of Mr. Gibson.
Technician Vs Performer: Danny describes Ninja Brian's style of musical writing as mathematical and based in music theory, whereas he does all his writing by ear.
Though some fan speculation claims that Danny magically replaces himself with the deliberately bad dummy they use as part of the band's deliberate Special Effects Failure.
Third Wheel: Brian comes off as a very creepy version of this at times, such as when he's casually sitting next to the bed with Danny and 'your mom' at the start of The Ultimate Sandwich, or when he's hanging out in Danny's bedroom while he's trying to seduce Kristen in The Sacred Chalice.
Party Of Three is essentially this trope, though Danny seems pretty cool with it. His date, however...
Up to Eleven: Unicorn Wizard is about if Danny was even more awesome than he already is.
Danny: What would my life be like if I turned that shit up to eleven (out of a possible five)?
