Shake Rust 

A phrase meant to say one is going to drive somewhere.
Derived from the fact many older vehicles will shake off rust when driven.

"Ah, I lost track of time, gotta shake rust."
"I'm gonna shake rust off to the store."

rusty protein shake 

When performing anal sex. the woman starts to turtle head as the man busts a load simultaniously. while this is happening the man grasps the womans hips and shakes her vigerously. thus a rusty protein shake.

I have to wash my bad sheets. my girl spilled my rusty protein shake all over it.
