Originating at Georgia Tech, in the fraternity house of Pi Kappa Phi, a "return to sender" is only successful with a partner. While receiving great head, the male must, without warning, ejaculate into the female's mouth. Lost in the confusion, the woman must swallow the semen and then proceed to vomit on the male's penis. The return to sender is a rare sight to witness and is rarely planned. If you have been on the giving or receiving end of this depraved sexual act, consider yourself lucky.
Bro: Dude, why was that chick running out of your room?
Brosef: Man that bitch gave me a return to sender.
Bro: Grody

A Shotgun/wootang that goes around an entire group of people smoking a blunt/cigarillo. While smoking either a blunt or cigarillo (filled with reefer) someone proceeds to give the person next to them a shotgun/wootang. Then the person who just recieved a shotgun/wootang holds his/her hit and gives the next person a shotgun/wootang. Keep sending the shotgun around until the last person gives the originator (person to give first shotgun/wootang) a monstrous shotgun/wootang. This works best with 3-4 people. It is important to remember to hold the hit you recieve to give the next person a shotgun/wootang with.
Man that 8 person return to sender was crazy.

That guy just died after the perfect return to sender.
