When a guys ass is hairy and makes the same noises as a Wookiee.
Get your Chewbacca Butt away from me.

Get the Chewbacca Butt mug.
When you fart and the sound that accompianies it sounds like Chewbacca's scream.
A guy is standing in the bathroom, tries to shit but only a Chewbacca butt comes out. Accordingly, the theme song to Empire Strikes Back starts to play through the intercom.
