This is just something that's bugged me a little in GTAV. When Franklin and Lamar are standing in front of Franklin's house for the first time, Lamar tells Franklin that he's got a "yee-yee-ass haircut". I know it's just dumb slang, but I'm always out of touch with dumb slang, and I've got to know if "yee-yee" is actually a thing.
It's in the video where Vinny plays GTAV, if you haven't seen it or don't remember it.
Hey, we live in a world where "yolo" and "hella" are actually things that people say, a handful probably unironically, this probably isn't too far-fetched.
