buttbolt 

A lightning fast shit, when you do a poop that shoots out.
Sometimes there is no need to wipe, its so fast.

Man I had a buttbolt this morning I didn't even need to wipe

buttbot 

Any automated program which does annoying things by design. Can be used to refer to a malfunctioning program, but this is not generally correct. Often used on chatrooms like IRC. Not to be confused with buttbutt.

"that program is a buttbot" - "the anti-spam program has buttbotted" - "the buttbot is on again"
