The worst inside joke (hand gesture) 

When you turn your hands into a claw like shape point your finger tips at each other and move them in a way as if your solving a rubrics cube then simultaneously making a deep sound similar to that of a whale making sweat love to a cow. Going a little something like this " Whab, whab, whab" This gesture can be used in many situations such as explaining lesbian sex to a young child teaching and telling your fiends this is what you did his/hers mom last night. The goal of this gesture is to instill fear and confusion.

Jack : "what the hell are you doing"
Tom : "Its what i did to your mother last night( while making "The worst inside joke (hand gesture)" ) "
