The act of rolling backward (or forward, in some rare situations) and simultaneously pulling down your pants, revealing your ass to the world.
1) Dude, Daniel was Video-Chatting with me last night, and he assrolled me! His bare ass was revealed to the world!
2) Care for an assroll?
3) Do you like assrolls?
Continuously being an asshole without a break.
I've pissed off five people in a row! I'm on a real assroll!
