These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Memetic Mutation: "Say it with ya chest, little ass nigga!" and "My momma said mind your goddamn motherfuckin' business!" both from Seriously Funny and "Alright alright alright!" and "The way my bank account is set up..." from Laugh at My Pain. Also "Bum bump", "Are you done?" and "Help me! Niggga!" from Let Me Explain.
What makes the "Alright, alright, alright" meme so hilarious that Kevin flat out tells the audience he's trying to make it into a meme, saying he wants everyone to be repeating it by the time the show is over.
Minority Show Ghetto: Averted. He's frequently cited by critics and box office analysts as an example of a minority actor who can attract white audiences, particularly with his Best Man movies.
Pop-Culture Isolation: He has been insanely popular in the black community since the late 00's but not so much in the mainstream, but he has started becoming popular in the mainstream.
