Bongo-Slamming 

When two males take a firm grasp of the opposing man's thighs and fervently bash butts.

An innocent fan walked into The Capitals locker room only to see the horrifying sight of Alex Ovechkin and Jamie Benn viciously bongo-slamming.

Biscuit Slamming 

The act of packing a can of raw biscuits up your lovers rectum with a broom handle, allowing them to marinate a few days, shitting them back out, then bake and enjoy!

Steven and Rob are having another of their famous “Biscuit Slamming” parties, and word is there will be some cream filled! Woot!

Bed Slamming 

To fuck inconsiderably hard, resulting in torn vaginas, chafed penises, and bloody sheets.

Rob and Tammy kept me up all night bed slamming in the guest room.
