1. Shaq, "Kobe, Tell Me How My Ass Tastes Freestyle"

Year: 2008
Lyric: Entire song.
How the hell is a random freestyle the best Shaq rap reference of all time? Easy, these few bars which were spit in a club just days after the Lakers lost in the Finals to the Boston Celtics are pure ether. "Kobe, tell me how my ass tastes," deserves a spot on the greatest rap disses of all time much less the top spot on this list. Salute and happy birthday to the Big Diesel!
