Hawian Switch
The act of having sex with a girl doggy style and making up an excuse to leave the room, then having a friend come in to take your place while you run out of the house and wave at her through a window.
Guy 1: Dude I totally pulled an Hawian Switch on her.
Guy 2: Did she flip out?
Guy 1: Well, my friends getting out of the hospital today.
