Wank-Shake 

A Wank-Shake is a filthy prank played by mcdonald's employees on innocent customers, who purchase any variety of milkshake, from a drive thru. to do this male employees will wack off into your milkshake thus creating a Wank-Shake. The symptoms of obtaining a Wank-Shake are: extra saltyness, your straw becoming blocked due to chilled spunk, stickyness after drinking milkshake and most of all, circular swirls of cream/white in your milkshake, due to a cheap attempt to cover it up.

Customer: "excuse me sir, i didn't want vanilla swirl in my milkshake!!"

Larry: "did you sort that posh twat in the mercedes a Wank-Shake".

Barry: "ov'coarse mate, a nice steamy one, Wank my cock!! haha!!!!"..

Larry: "Lerious-character!!! hahaha!!".

Wankshake

When you haven't washed your hands since you last had a wank and have now found yourself shaking hands with somebody important.

Dave shook hands with his girlfriends father. He remembered how he hadn't washed his hands since having a wank and awkwardly made eye contact with him. It was a Wankshake!
