S.C.A.T. stands for "Special Cybernetic Attack Team", But "the droppings of carnivorous mammals" is what "scat" really means! It's as close as you can get To a Nintendo game called S.H.I.T.!
Unstoppable Rage: After accidentally hitting Start instead of Continue in a heated game of Predator (which starts a new game rather than continuing where you left off) near the end of the Schwarzenegger episode, the Nerd goes ballistic and declares once and for all he's going to beat this thing! Which he does despite its bad design and Nintendo Hardness.
Also, when after beating Ghosts 'n' Goblins for the first time in 25 YEARS, he finds out that you have to complete the game twice in one sitting for it to count as beaten.
Nerd: You have to beat the game twice? You have to beat the game twice in a row! (laughs in quiet anger) Well, that's just great, because now I'm twice as fucking pissed off!!!
Unusual Euphemism: The Nerd is fond of using "ass" and "fuck" in place of other profanities, such as "What the...?!" or "Son of a...!" Not that he isn't willing to use legitimate swears, of course...
Updated Re-release: Has recently been uploading higher quality versions of his older episodes.
Up to Eleven: In his "Dragon's Lair" review, he found it odd that most of the time, you die in one hit, yet the bat only takes away one unit of health, and eleven hits from a bat will kill you. "Why ten, when it can take eleven?"
Metron: By sparing that shitty game, you have demonstrated the advanced restraint of mercy. AVGN: Mercy this, motherfucker! [shoots the Metron]
Video Review Show: He is so prominent in this domain that almost anyone else who attempts to do this has a high chance of getting a They Copied It, So It Sucks reception. The spin-off series Board James differs from the main series in that it lies far on the "Show" end of the scale.
Viewers Are Morons: Notes this in Back to the Future Re-Revisited when most of the levels are the same running stage only colored differently. "Do they think we're idiots?"
Waxing Lyrical: In his first "Ghostbusters" game review, he pondered why you're capturing ghosts if they're not harming anything, and asks: "Because busting makes you feel good?", a line from the Ghostbusters theme song.
Also, from the Tiger Electronics episode: "Yeah, this Tiger sure rose up to the challenge of its rivals, had the guts, got the glory, went the distance, now it's not gonna stop! It's literally a survivor!"
Well-Intentioned Extremist: R.O.B. wants to turn all games into Gyromite and Stack-Up because the Video Game Crash of 1983 was a result of the market being oversaturated by shitty games. He tells the Nerd that in this new world, all the things he came to hate about games would be gone.
What Is This, X?: In the Game Glitch episode, the Nerd is distracted by the Glitch Gremlin messing up Rocky Balboa (Bug-Eyed Balboa) and Spider Rico (Spider Rico with no jaw) on the Rocky PS2 game:
AVGN: They're like zombies! What is this, "Rocky: The Undead Edition"? You are really one sick fuck, you know that?
In the Pong episode:
AVGN: You get 4 different kinds of Pong, like... [The TV screen shows two walls with small holes replacing the paddles] AVGN: ...what the hell is this, Reverse Pong? Okay... [The TV screen shows one regular paddle at the left and an extra long paddle at the right] AVGN: Oh, now what's this? Asshole Pong? That's not fair!
The Bill and Ted NES review finally gives us what LJN were thinking: they weren't thinking.
When He Smiles: If you only know Rolfe as the Angry Video Game Nerd, even seeing him corpse during outtakes can be endearing, if not a little jarring.
Wilhelm Scream: The Nerd gets one courtesy of Super Mecha Death Christ 2000 for swearing in The Wizard and Mario Bros. 3 review. What makes it more amusing was that Super Mecha Death Christ 2000 was swearing more than The Nerd.
Wham Shot: In Wish List Part 2: When the nerd plays a decent Spider-Man game, he looks to see who made it. He finds the LJN logo.
The Nerd is ecstatic at the beginning of the Nintendo World Championships episode, as he believes he has purchased a box of games containing one of the incredibly rare original cartridges which would normally be unimaginably expensive. It turns out to be a dime-a-dozen reproduction cart.But at the bottom of the box, however...
Taken even further when he actually plays the game. He is not happy to find out that this ultra-rare, ungodly expensive game is actually just a very short compilation of other common games.
At the end of the first Terminator review, the Nerd said that they've gotten some really bad Terminator games out of the way, so from here on out, the Terminator games should improve in quality. But then he looks at the front of the Terminator 2 NES cartridge, where LJN's logo is shown, and gets a horrified look.
After beating Ghosts 'n' Goblins for the first time in twenty-five years, the Nerd just looks so happy that you can't help but smile with him. Then he learns that the game has to be beaten twice in one sitting to count as total victory. See Unstoppable Rage.
You Have Got to Be Kidding Me!: The Nerd's reaction to finding out that in order to find the last digit of a phone number in "Bill and Ted's Excellent Video Game Adventure", you have to blast the phone booth symbol out into empty space to find two pink skulls that may or may not have the final digit.
Your Head A Splode: Occasionally, he mimes this when he's especially confused by something. The best example would have to be at the end of his Rambo review, when he falls out of his chair.
You Keep Using That Word: The Nerd seems to use the word "asshole" as referring to an idiot, rather than its more common meaning. For example, in his Virtual Boy review, he states that no one would want to wear the console in public because "you look like an asshole".
Nerd: Okay, whoever came up with this is—(message from in-game Nerd appears)—yeah, exactly. They read my mind. They're an asshole, which means that the asshole who made this game acknowledges that they're an asshole and that I called them an asshole! You asshole.
Also, from the same episode:
Nerd: It's the Giant Claw. It's as big as a battleship! How did it get in this game? It just barged right in, like a battleship crashing into a harbor. It's taken so many hits, like bullets on a battleship! It's a flying battleship!
In the Nerd's case, it's less of using the word improperly and more that he considers buffoonery and idiocyto be offensive and stupid things have a way of making it seem like the world/videogames are having fun at his expense. So, not exactly unjustified.
As shown below, he also uses "Your Mother!" as a generic curse, which is a rather unusual usage of the term. It's hilarious because of how instinctively it comes out.
Possessed cartridge: "I said, your mother sucks cocks in hell!!!"
Also during one of his many deaths in his Silver Surfer review:
"Aw fuck! Your mother!"
During his Dick Tracy review, he grunts "ugh, your mother!" while trying to grab a seemingly unreachable clue.
In the Ninja Gaiden episode, when he fails at one part in the game:
"Ugh, your mother!!!"
Predator (NES) "is as ugly and dirty as this game's mom."
In Part I of the Castlevania-a-Thon, when he finally beats the first Castlevania, he triumphantly throws down the controller and yells, "Your mother!!" while brandishing a fist.
Your Princess Is in Another Castle: In the "Bugs Bunny's Crazy Castle" episode, just when the Nerd thinks he has beaten Bugs Bunny into submission, an Iris Out starts occurring, about to signify the end, but Bugs pops the iris back open, indicating that he's not done yet, and the episode still continues.
