When you're about to get head from your lady friend, shave in preparation and keep a handful of your pubes. Then, pull out unexpectedly and skizz on her face, throwing the handful of pubes at her so they stick to her now-gooey face.
The fuzzy glare you recieve is a sign that you now have an Angry Ewok.
(Helps especially if she's a midget.)
Dude, I pulled an Angry Ewok last night!
Man you're such a Star Wars nerd.
Yeah, apparently your mom isn't.
