something you call someone when they are being strange cheese eating birds. they usually will insult you with the
line "you deformed animal cracker eating vegetarian." they also might say "you look like a hippopatmus booger monkey that just went on a weight watchers diet."
I love my boyfriend, even though sometimes he is a jerkbutt! (:

a very rude person who is being a jerk. somebody who just cant be described as anything else.

A person who you dont want to call an ass cause you wanna be nice. so you call them a jerk but instead to make it sound a little better.
your being such a jerk butt
