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.
Their music contains examples of:
Acting for Two: The post office worker and zookeeper in No Reason Boner are voiced and played by Brian Wecht, simply without his ninja mask on.
In addition, though the Manticore's full face is never seen, he never is onscreen at the same time as Brian.
Actor Allusion: "Why is that guy naked?" in Let's Get This Terrible Party Started. The naked guy is played by Xan Alda. Also from that video: Barry and Alex Kramer are part of the Jewish country band that are hired.
Ninja Brian as Albert Einstein in Dinosaur Laser Fight, and Danny as romance and Brian as science in Sex Training.
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.
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.
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).
A Date with Rosie Palms: Next To You, where Danny gets rejected by a girl but says he's happy to just be friends. He then spends the entire video stalking her while masturbating.
Death Is Cheap: No matter how many times Brian slaughters Danny, he's always back for more.
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.
A fan theory exists that the first verse is simply Danny singing from Brian's point of view, and then his own in the second.
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. We have yet to see or hear from them, though.
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.
No, Except Yes: "Oh, hey, Ninja Brian, that came out wrong. I didn't mean to call you fat. I meant stupid. And ugly. And fat."
Prop Recycling: Danny's weapon in the Dragon Slayer music video is a replica of the Staff of Parthalan from Dragon Age II, lent to them by Holly Conrad, who made it for a cosplay in 2011. Unfortunately, Brian accidentally dropped and broke it after filming. Danny later wrote Holly a heartfelt apology letter◊.
Psychic Powers: On three occasions, Ninja Brian has shown to have the ability to cause people, buildings, and even the sun to explode with his mind.
Danny: Alright this party sucks, Ninja Brian, explode this building with your mind.
Raging Stiffie: Danny tends to get these a lot. Particularly featured in the aptly named No Reason Boner.
Recurring Extra: Dan Hodapp, known as the character Roger Rogerson, appears in the vast majority of their videos.
Danny's Game Grumps co-stars, Arin, Ross and Barry have been showing up regularly in their more recent videos.
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.
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.
Take That: When listing the things that Brian likes to suck (dicks), one of the images that flashes by is Mel 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)?
