USC legend LenDale White was so furious after watching his alma mater lose to Tulane that he took to social media to unload on the team ... at one point calling the Trojans defense "a f***ing joke."
Lincoln Riley's offense looked good against the Green Wave in Monday morning's Cotton Bowl -- but the defense ultimately let the team down ... giving up a game-winning TD with just seconds left to lose the contest, 46-45.
White was HOT about it all immediately afterward on Twitter .
