When a guy is getting a gal up the booty with his ding-a-ling and one of his guy friends, who has been waiting in the closet, sneaks up and puts his ding-a-ling in immediately after the 1st guy "accidentally" pulls out. Then the 1st guy sneaks runs outside and knocks on the window to inform his gal that she has received the boogeyman. This act is used to pay a bitch back or to get a lonely friend some ass.
Guy: Hey (place guys name here), do you want to give (place girls name here) the boogeyman tonight?

Friend: Yes, I'd love to stick my "D" in her "B"...lets do it!
