to insert your penis on the zipper and zip up, causing massive devastation to your penis.
Dude, I was bored one night, and saw my zipper jacket on the floor. SO I decided to zipper fuck it. Not a very good idea beacuse now my dick looks like a pot-sticker.

Fucking somebody without expectations of dating, but with numbers and contact information being exchanged (making it different than a one night stand). Random sex for fun, but not having any regrets.
Last night I zipper fucked this guy....
