Mexican Zamboni
When a person defecates on another person's chest and proceeds to sit on their chest and spread the feces around as if a zamboni would on an ice rink.
I started out giving that a girl a Hot Carl, but then decided to finish it off and give her a Mexican Zamboni.
Mexican Zamboni
When you sit on someone's chest and take a hot steaming dump and then proceed to scoot around their chest and stomach like a dog in order to create a smooth, slippery, warm layer of shit; much like a Zamboni does to an ice rink.
My girl didn't wanna bone because it was too cold, so I gave that ho a Mexican Zamboni, and we were good to go
