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.

when you go at it so hard that your balls get hard as well. the thrusting & smashing that goes on for hours becomes so exhausting. you stand there, in & out. when you finally release your steamy, hot, cum it shoots through that pussy & that shit becomes a flapper. the moans are immaculate, echoing off the walls around you. after this type of orgasm your nuts will never be the same. & the chick you smashed will have a grandma cooch for life.
zoe: dude i smashed andrew so hard last night, he gave me a flapper! turns out at the end of that, he had a hard sack!!
