*opens door* "Oh hey, it's that guy who's never going to appear on screen at the same time as me."
Also his Cousin Timmy (a parody of Irate Gamer's Cousin Joey character), who is obviously just TRG in a hat while slightly bending over.
Adaptation Displacement: invoked Enforced, exaggerated and parodied, due to the Irate Gamer frequently getting the facts about a game's source material wrong. For example: In the Super Mario review, the Third Rate Gamer thinks that the Super Mario Bros. film is the original and the game is just a cheap licensed cash-in.
Well fine! I don't need you, I'll just do this review by my... *looks at script* self!
Big Lipped Alligator Moment:invoked Quite intentional, to parody the Irate Gamer's tendency to shoehorn random characters in his reviews.
"Why do I keep putting these interruptions into my show?!"
Blatant Lies: In the middle of his Kirby's Adventure review, he does a slight commercial break advertising a card game. We then cut to an actor who is not very enthusiastic about his opinion, and the bottom of the screen has a caption saying "NOT A PAID ACTOR".
Bleep Dammit: Parodied in the Yoshis Island "review". Certain words like "shit" and "fuck" are partially bleeped out, usually in a way that makes it really obvious what the swear was. However, words like "dickwaffles" and "crap" are kept.
Buffy Speak: "In the old commercials, he (Cool Spot) would walk around and stuff."
Captain Ersatz: Billy is an obvious parody of Irate Gamer's side character Tony, complete with a dumb nonsensical catchphrase and being represented by a sprite taken from a browser-based MMORPG (Runescape rather than MapleStory here).
Captain Obvious: Played for Laughs. He circles very easy to see things, and points out things the viewer can plainly see, like mentioning that each stage is harder than the last.
Continuity Cavalcade: Parodied. At the end of his Chip & Dale review, all of the minor characters from previous episodes appear to watch the ending of the game, including Flashter, Offensive Stereotype, Ryu, Cool Spot, Wilkins, and others. This is a parody of the time Irate Gamer did the same thing.
Covers Always Lie: He points this out on the cover of Castlevania, in regards to the sword Simon Belmont doesn't have in the game.
"As you start playing you'll notice this horrendously horrendous music. It's driving me insane! Listen to it too much and it'll drive you to brink of insanity! This music is so bad that I'm about to go insane!
"Super Mario Bros 2 is a video game created by Nintendo for the Nintendo NES System System made by Nintendo.''
Incredibly Lame Pun: "I said Goros, not Gurus, dumbass!", in a reversal of a lame pun the Irate Gamer made.
Know-Nothing Know-It-All: His general character. He'll happily launch into tirades about a game's history while getting every single fact wrong, and whenever he shows footage of himself playing a game, he's doing horribly.
At the beginning of his Chip n' Dale review, he complains there is no two-player mode, but he really just hid the option and said they buried it too deep into the menu. This was to parody IG's Tekken 6 review.
"I know what you're thinking — that I'm going to sit here and bash Super Mario 2. But before you start sending your hate mail, just hear me out. Now, I don't hate Mario 2, but when compared to the other Mario games, this one just has "ass" written all over it!"
Off with His Head!: This happened to him at the end of his Ninja Gaiden review, where the Ryu sprite comes across the screen, "chops" TRG's head off—really poorly, BTW—and the screen displays technicolor strobe lights with the Ninja Gaiden failure music and its "Game Over" screen.
Only Sane Man: Billy is quick to point out the Third Rate Gamer's idiocy.
Pac Man Fever: Parodied. In every reaction shot, he's constantly button-mashing, regardless if this makes any kind of sense for the game sequence in question. He's almost always using a controller from a completely different system, and sometimes not even a controller at all, like a pair of headphones and the DS case for Final Fantasy III.
Plot Hole: Poked fun at in his Chip n' Dale review; Cool Spot shows up the way he usually did in TRG's review of said game, but Billy quickly calls him out on this since Cool Spot was supposed to be dead. TRG responds with "Who's going to notice?" This is a stab at the same plot hole with Kool-Aid Man in IG's review of Cool Spot.
Poe's Law: There is a worrying amount of people who fail to realize he's a parody, if the YouTube comments are anything to go by.
When TRG dies in an explosion that leaves his house unharmed, the newspaper says, "Third Rate Gamer killed by lame special effect".
In the Little Nemo review, he shows obvious clip art of a kid on a bike (with his face plastered over it) that still has a white background moving in an obviously-fake manner over another picture of a house.
The entire series is one big Take That to the Irate Gamer. Also occasional jabs at Leisuresuitgaming and Game Dude.
This even goes as far to have a Take That to one of The Irate Gamer's Take Thats, when he says, "Well, yeah, but these haters are...dumb." (Photoshopped graphic saying "PWNED!")
And occasionally, he goes for targets other than video game reviewers.
"This ninja is the worst ninja in the history of ninjas! I'd rather watch an episode of fuckin' Naruto than play a level of this shitty fake ninja game!"
They Changed It, Now It Sucks: Parodied in-universe in the Yoshis Island "review", where TRG complains a lot about everything in the game that's different from other Mario games, even minor things like the fact that you can jump on Shy Guys to kill them, but you can't pick them up.
"Hopefully if I circle these words as I read them, it will enhance the video because my fans don't know how to read."
Wanton Cruelty to the Common Comma: Parodied. He mispronounces words that the Irate Gamer frequently mispronounces, such as "fustrating" and "emenies", fails at grammar, or uses the wrong word ("predecessor" for "successor").
