If I Die 2Nite is used in two ways here.
-Pimp C is a fan of West Coast rap, and, in this case, raps that he enjoys Tupac’s music, one of the songs being If I Die 2Nite
-Second usage is the literal meaning of the song’s title bringing up the hypothetical situation where Pimp C dies tragically due to his violent lifestyle. This possibility is always looming, so Pimp C takes consolation in the fact that he’s made something of himself, and his mother could be proud that he didn’t die after not accomplishing anything
This is either incomplete or partially wrong:
Young Jeezy is based out of Atlanta; the part about Detroit either references something else or is a play-on-words since snow means cocaine and Young Jeezy is also called “Snowman” due to his roots with the drug game
He’s actually referencing Rap-a-Lot Records which had the famous Geto Boys, as referenced in the next line
Also a reference to one of his songs, “Put On”
A crip is also referred to as a crab
He’s talking about Too $hort whose nickname is Short Dawg (ie. the part about being the “real” one)
