The metric unit used for measuring masses in the quanities that one average-sized butt can hold. Can also be with the subfixes... kilobutt-load, megabutt-load, nanobutt-load, and so on. Gay people like to use this as a reference.
Jack: Yeah so I found this apple in the store, it was HUGE! Probably about one megabutt-load!
Sally: Whoa, maybe if youre gay.

"A butt-load chad? How much is a butt-load? Da Doug! 1000 Dollars. Based on the fact this one time I shoved 5 dollars up my butt and I know I could fit way more up there. Way more! Easy!
