Mawhole
A mawhole is a huge gaping hole of an ass given to you by bigfoot kicking you with his WADs (Weapons of Ass Destruction) closely related to WMDs. Bigfoot's WAD is his huge ass feet and he kicks you right in the ass leaving a gaping maw of a asshole leading to a mawhole.
I was doing a beef jerky commercial for jack links and i was messing with bigfoot when suddenly he kicked me in my ass and left me with a mawhole. That son of a bitch.
