Ja Rule, hip hop culture's whipping boy and worst rapper of all time. His name is used to define any situation in which you are going to get super trashed, feel like you have been "a little too fucked up" or got the short end of the stick.
When you're street racing for pinks and you lose, but still expect some booty from Monica afterward.
"Fuck dude, I got a little too Ja Ruled at the party. I had to fucking peace early."
"Get Ja'd bitches"
"Those kids really Ja'd me on the deal."
