The act of slathering one’s chocolate icing donut onto the asshole of your partner and then licking it clean
P1: What did you do this weekend Brecky?
Brecky: I found this random guy on Bender who came over and gave me Mudbutt.
P1: OMG Brecky!, what’s Mudbutt?
Brecky: It’s when he smears a chocolate iced donut down your shit box and then licks it clean
*For the Boston Hot Box a Boston Crème donut is substituted
