When one while fingering a girl decides to surprise attack the butthole with a thumb. Usually starts with a loud hawk screech to notify the girl what is about to happen.
Girl- "moaning"
Guy- "WREAEAH" *inserts thumb
Girl- *Smack
Guy- "laughs it off"
Cindy- You look pissed
Amanda- well thats because tom gave me a sneaky talon last night.
Cindy- Ouch
