Buttmuff
A Butthole.....basically
Jimmy stuck it in her buttmuff happily
Buttmuff
Affectionately refers to the national forest or jungle of hair protecting the dark canyon of anal bliss, the shield to the turdcutter if you may. This thick mane which sprouts from thine crack makes it necessary to use a TurboJet 9000 to clear out butt butter and Klingons.
As I raised my feet toward the heavens and spread my cheeks for my boyfriend, I could feel my buttmuff wafting in the breeze like a field of barley.
