most likely originated in Australia or new Zealand, due to one of the main livestock being a sheep

A sheep's testicles

You can't eat mountain oysters...unless you're into that.

Goat and Oyster

The psychological disorder when two friends hang out so much that their friendship borders on codependency, and they only act out when around each other. This results in dick riding that is usually harmless but can turn into chronic douchebaggery if undiagnosed.

Me: those guys are really cool, but not when they act like batman and robin. Its unhealthy.

Jesh: yeah dude, they are totally goat and oyster.

shucking oyster

to take a girls virginity, playing on the slang word for vagina as a "clam": meaning cracking that pussy open and indulging in the inner beauty of the female body.

Jordan- what ever happened with that girl last night?
Mackie- I totally shucked her oyster.

morning oyster

Coughing up detritus from the lining of the throat and lungs,usually associated with smoking and drinking the night before,usually in a liquidy-greenish spot,with,erm,...bits ;)

I woke up this morning after that clubbing session,and it felt like I had sandpaper in my throat,and baffles in my lungs. I had a long drink of water for my throat,and a good old hoik over the verandah for a morning oyster

Dockers oyster

Lumpy mucous excreted from the lungs whilst coughing. Apparently, dockers had rather a lot, and were never likely to be able to afford the real thing!

After spitting.. 'there goes another dockers oyster'

Sandy Oyster

This is when you are fucking a fat bitch on the beach and you think you are fucking her big fat stinky pussy but you are really fucking a fold of fat that is filled with slimy moldy crap and sand.

Guy: That was a great fuck. I have never felt a pussy like yours. I always wanted to fuck a fat bitch on the beach. Like a beached whale!

Fat Bitch: I did not feel anything, you were fucking my sandy oyster.
