Mondo Handshake

While having anal sex with a girl, you reach around insert your fist into her vagina and give yourself a hand job through the lining.

I was having sex with a stripper who had a loose buthole, so I reached around and fisted her equally lose vagina and squeezed my penis through the lining to give myself a mondo handshake!

Mondo Bizzarro 

This is when you and your buddy lay the wood to your respective girls...on the same bed

I wanted to see my boys girlfriend's tits, but he wouldn't let me do her. He instead offered a little mondo bizarro action last night.
