stands for "Dude, I got four" when responding to an inquiry concerning the length of ones dick. Often used by 12yr olds when trying to appear cool, but are completely oblivious to it's actual definition. Can often be found scrawled on bathroom walls, tables at taco bell, the side of buildings, or pretty much any surface then be scratched, burned, or retain ink of any form.

(silence...)
