There's a bunch of things all characters say, especially these ones...
"OG-Loc, OG- Joke. That's more like it" (one of his girlfriends)
"Car crashes are so erotic" (same girlfriend)
"Keep talking, That's amazing, Oh really, Uhu uhu" (CJ when driving with his girlfriends)
"I ain't insecure but tell me I'm the best, You should get paid for this, I love you girl, I hope you're girl" " (CJ when having some "Hot Coffee")
Tha funniest conversation: Between CJ and Sweet talking about the British guy that jerks off all the time (Dr. Jerkov)
And my favorite quote "I smoke 'cause it gives me knowledge" (a pedestrian)
