Bad. Describes anything that sucks.

Originated as a combination of "craptastic" and "ass" (ie. sucks ass)
"Dude. I totally suck."
"I know man, you're totally asstic."
"Okay."

The amount of ass particularly from the female sex that bounces during doggy-style sex.

The amount of her assticity was amazing.
