First discovered as an "ancient" Chinese massage technique, it has now adopted into a childhood assault tactic.
It is started by sticking a
single index finger into another's
anus. This is followed by a loud cheer of "Sippie Sou
Wow!" from the giver.
Dude don't go to that massage parlor, I asked that cute
Asian chick for a happy ending and she stuck her finger in my ass.
Girl 1: "Sippie Sou
Wow!"
Guy 2: "Gah!
Grace wtf!"
