Driver: Yo that car in back of me just flicked me off
Passenger: dude u want me to charley Brown him
after finding out a girl or guy(if ur gay), is cheating on them,they request a blumpkin, right before ejaculation, sit up and dunk the cheatee's head in the toilet without warning for 5 seconds. After releasing the cheat, and letting them gasp for air, their face gets busted on....
Leon cheated on his shemale and as a result, received a midnight charley brown.
