True Def

One who doesn't have a clue what the hell they are saying.

A kid that goes to Starkville and gets messed up.
Dumbs that have trucks but don't use them.
People that dip.
Anyone that thinks they are a bulldog.
Anybody that chides

Wow, that kid is being a true def!

Def O.J.

The term "def OJ" from Rapper's Delight by Sugar Hill Gang is a dated reference to O.J. Simpson, who before killing his wife was the spokesman for Hertz Rental Car. It means a fast, flashy car.

"get a fly girl, drive off in a def O.J."
