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.

Lamington Slammington 

The act of compressing a lamington with your hands and then trying to consume it all in one mouthful.

Zak proceeded to launch lamington everywhere like a grotty cunt in an attempt to consume it.

Slarmin' Hard 

To do completely unproductive things (surf teh interwebs for pictures of pugs in clothes, watch an entire season of Dr. Who, eat massive amounts of chicken wangs) for excessive amounts of time, especially while in a ridiculously relaxed/possibly unhygienic state.

I'm sorry I couldn't make it to your Bar Mitzvah, Timmy, I was too busy slarmin' hard.
