A piece of shit that gets flattened in between the cheeks of your ass (after an early morning dump), and throughout the course of a day, it dries and becomes brittle, just like a cracker
Man I need to go home and get rid of this huge butt cracker, it's starting to itch.
When a person has a mom or dad thats a mexican, and his other parent is white.
Mark-man that guy is such a butt-cracker.
Harro-yeah his dad's a mexican.
