A code phrase between males. "
Part 3" can be anything sexual you want it to be. It can be making out with a girl,
throwing a bone at a girl, or anything you want with a girl. It is usually sexual intercourse in which the reproductive parts are put into action. It is used by males around their girlfriends to trick them into agreeing for a "
part 3". Then, you would brag to your guy friends by saying that you've had a "part 3."
This follows
part 1 and part 2.
