back sack attack

The assault of one's testicles from behind. Generally, the victim is bent over, however a standing attack up the legs is also commonplace.

Often times, the assailant will yell "back sack attack!" either at contact, or after the strike is complete.

Winding up for a kick, Ben positioned himself behind a bent-over Matt. Using mostly the flick of his foot unto the scrotum, Ben yelled "Back sack attack!" before Matt ever got the chance to react. Devolving into his fetal position, Matt sat writhing in pain.

sack bump

An elaborate, ceremonious salutation between close male friends. When two friends who haven't seen each other in a long time are reunited, they immediately drop trow revealing their sacks, then hold them in an outward-facing position and run directly at each other. This is typically executed at full speed and in perfect alignment. The result is that both participants dangerously collide sack-first, causing them to repel off of each other in a cartoon-like, elastic fashion, ultimately sending each friend into random, disoriented trajectories where hazards likely await.

The sack bump is a kin to the well-known chest bump and fist bump. However, the sack bump is a superior and more valued greeting ritual, reserved for parties who hold the utmost respect for one another.

The epic sack bump of '89 sent Gordon off a balcony, shattering both his legs and his penis, while long-time friend Herbert was hurled under a taxi cab, bursting his coin purse apart instantly on impact.
