Slamman 

The scourge of GTAForums.com, acts like a hobo and is a greasy long-haired slob that sits around on his PC creating useless topics and making useless posts on GTAForums. He is one of the least respected people over there and is generally treated as the village idiot.

Slamman: I had to sell my PSP to pay the rent.
GTAForums Member: Good for you, no one cares.

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!

Jersey Slamma-Jamma 

This takes preparation. You need to be on the verge of a constipated poop. In other words, a solid shit. While performing anal, doggy style, you stealthily shit in your hand. In one fluid motion, you pull your cock out and slam the shit in the gaping hole, and immediately JAM your cock back in.

I haven't shit in a week, I'm going to give her a great Jersey Slamma-Jamma.

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 do the lamington slammington".

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

Slampanion 

A companion that you have an agreement with to slam whenever is convenient.

Kevin: 'Are you guys dating?'
Max: 'Nah man, we're slampanions'
