When a girl is laying on her back and you are balls deep in her pussy and she farts causing your balls to shake violently.

The act of fisting a girl while she is on her period. When you are finished fisting her, you pull out your hand spread wide open like a bat leaving the gates of hell.
I had my period last night and Gary decided to fist me. I thought it was weird, but then he pulled out his hand and screamed "Fly, Fly away like a bat out of hell!!!!!"
