What is Ass-butts?
(Ass-buhttz) n. 1. Used as blatant redundancy to prove unnecessary terminology. 2. A negative nick-name.
When one says something of ill-intellect such as: "You're the most awesomest person I've ever met!". That is the equivalent of saying "most most awesome". At this point, one could say "Stop bein' such an ass-butt".
"Dude, you know those people who say "Irregardless"?
Those guys are such ass-butts"
