Hair-noose surprise 

When one wraps his partners hair around her neck, holding onto it firmly from behind, and places a thumb just behind her anus. With a swift tug, pull back on the hair and insert the thumb shouting "surprise".

Dude - the chick hasn't talked to me since the hair-noose surprise.

Did you shout surprise?
No
Well that would be why then!
