Dirty Oyster

When you have a chest infection, but still keen to give oral sex to your significant other. So you cough up a bit of green phlegm and spit it on them down under for a bit of extra lubrication.

Friend: "Hey, how have you been with this chest cold lately?"
"Yeah, good I gave my partner the Dirty Oyster last night."
Friend: "Oh that's nasty man."

It gives the experience of a night out at bad seafood restaurant without having to spend any money.

Dave: "Shall we go to the new seafood restaurant on the shore?"

Matt:"Nah, we can just cut to the chase with a quick Nasty Oyster"

Oyster Clamp

One of the various phrases used to describe the act in which a woman rubs her vulva against her partner's body for the purpose of sexual pleasure. In this case, an Oyster Clamp occurs when the lips are sticking due to the lack of lubrication and are firmly pressed together so that they become interlocked or "clamped."
