1. a "fizzbitch" is when you're fucking a girl, but pull out right before you cum and bust in her belly button. then you scoop it out with your fingers and either stick it in her ear or slap her in the face with it.

2. it could also be used as an insult.
1. Glenn was fucking some fat chick the other day and gave her the fizzbitch

2. Goddammit Eric, why do you gotta be such a fizzbitch all the time?!

Get the fizzbitch mug.
Someone who gets raped up the ass, but instead of using lube, the rapist uses pop rocks. This causes the person being raped to experience a painful fizz (in addition to the pain of being raped).

The term fizzbitch is typically used for people who are regularly raped with pop rocks.
"Check out the fizzbitch, I heard she took it up the ass again last night"
