Nigahiga (real name Ryan Higa) is currently the seventh most subscribed person on Youtube with over 9 million subscribers. He has six main video types:
His "How to be" guides, all of which were originally taken down because of copyright, but now some of them have been readded. These include "How to be Emo", "How to be Gangster", "How to be Ninja", and, among the still-removed ones, "How to be Nerd" and "How to be UFC Fighter";
His "Off the Pill rants", where he talks about anything that bugs him while staying off his A.D.H.D medicine (hence the title);
"Movies in Minutes", which are movie spoofs in, well, minutes;
The "Skitzo" productions, which involve him and three of his personas: R-Dizzle, Hanate, and Regina.
And "Dear Ryan", where Ryan humorously answer questions people ask in Youtube comments.
One of his most recent projects was an internet movie he created with Wong Fu Productions called "Agents of Secret Stuff". Tropes exclusively from A.S.S. (teehee) should be placed below examples from the regular videos.YMMV page here.
A.I. Is a Crapshoot: The iNavigator is not evil in any ways, but it tends to piss the user off by its inefficiencies.
The Google Glass Human is more malignant, guiding its user into a pool, automatically turning down dates, and downright refusing commands. It eventually ends up killing its user via Fartillery, or "Am Fragrance".
Boastful Rap: Discussed in "Off the Pill: Arrogant People", where Ryan notes that many songs on the market are very self-promoting. He then imagines what "Look at Me Now" would sound like if Chris Brown was modest.
Brand X: In 5 Steps To Be Badass, where Ryan holds a can of "Beer Light" that's just a Bud Light can with a piece of tape with writing on it slapped over it.
But Wait, There's More!: Often, but especially prominent in the Children's Bop commercial, which came with Puberty Bob, Speech Impediment Stuttering Bop, and a free order of Bi Bim Bap.
The Cameo: Ryan's brother made one in his "Off the Pill: Weird People" video, who appeared so quickly and said so little that some mistook him for Ryan himself. Also, New York Knicks Ensemble Dark Horse Jeremy Lin (back then a member of the Golden State Warriors) made a cameo in the "Daily Life of a Basketballer" video. Ryan himself cameoed in Lin's own "How to get into Harvard" video.
Double Standard: Discussed in "Off the Pill - Feminist", where he especially questions why females consider compliments to their breasts offensive while males don't do the same about compliments to their muscles.
Dream Team: As of late he's been doing collaborations with the other Los Angeles YouTube stars, such as Kev Jumba, Chester See, David Choi, and D-Trix. He is also a part of a group called YTF consisting of himself, Kevin, Chester, Victor Kim, Andrew Garcia, JRA and D-Trix.
He is also good friends with many Asian American Youtubers, like Wong Fu Productions, Arden Cho, Cathy Nguyen among others.
Hand or Object Underwear: Parodied in the Carl's Jr. New Portobello Mushroom burger ad, where he quickly names all the things the burger can do; "censor-covering" has him with a box containing the burger over each nipple.
Japanese Ranguage: The personal trainers in "How to be Ninja" speak rather inconsistently this way. This carries into Hanate's appearance on Skitzo. Also counts as N-Word Privileges, since both Ryan and Sean are Japanese.
Kiai: The first step to being a Ninja is to make loud, unnecessary sounds when you hit things.
Master Ching Ching does this in "Ninja Melk" because he's played by Tarynn Nago in a mask.
Mind Screw: The aptly named "Dafuq Did I Just Watch?"
Motor Mouth: Welllooknofurtherthankstothebigbouncinginflatablegreenballyou'llnotevernothaveaballagain!
What did he just say?
Mr. Fanservice: Click on one of his song parodies, "Like a Good Boy." Read the comments. Drink a glass of water every time you see a comment talking about how hot he is when he takes off his shirt in the video for just a few seconds. You will be spending a LONG time in the bathroom.
Multinational Team: YTF. Ryan is Japanese. Kevin's Taiwanese. Victor Kim is Korean. Andrew is Latino. JR is Filipino. D-Trix is part-Filipino, part-Latino. Chester's half-Filipino.
Nice Guy: Ryan and Kevin in "Nice Guys" start out as this, become jerks, and then go back after realizing girls don't like jerks.
No Budget: Unlike many professional Youtube stars, all his videos are done with just iMovie, a few items around the house, and a few other people. Yet he's got about 10 million subscribers and is well known throughout the internet. Heck, the videos that got them to fame were in fact amateur How-To videos that were put up on Youtube to show his friends!
Put on a Bus: Ryan's sidekick, Sean. In "3,000,000 Subscribers" he made a cameo and revealed the reason he hasn't been around a lot was because of his going to college far away. He also cameoed in "2012: End of the World" and "Bromance".
A Running Gag is that Ryan somehow "replaced" him after intentionally putting him on the bus. (This was a joke, and for some reason many people took it seriously...)
The rest of Yabo Productions disappeared at some point, including Ryan's ex-girlfriend Tarynn.
Poke the Poodle: In "How to be Gangster," there's a sign in the car that says "Never Drink and Drive." Cut to Ryan driving and drinking...a juice pouch.
Why Don't You Just Shoot Him?: Lampshaded when Ryan fights his Evil Twin. When evil Ryan beats the real Ryan in a fist fight, he pulls out a gun to finish him off, and the real Ryan asks why he didn't just do that earlier.
