#5. Young Jeezy

Unforgivable offense: The origins of this supposed beef aren’t completely clear. Jeezy was friends with Black Mafia Familyl kingpin Big Meech, and on a freestyle over Ross’ “BMF” called “Death B4 Dishonor” he rapped, “How you blowin' money fast/You don't know the crew/Oh, you part of the fam?/Shit, I never knew.” Some interpreted the line as shots, although Jeezy has insisted in interviews that he has no beef with Ross. 

His punishment: Flunked from Thug Motivation 103, forced to repeat.

Complex says: The real winner of this beef is Def Jam.
