While back-to-back,
one person farts into another person's
butthole. Then the second person farts out that
fart creating a refart.
Potentially dangerous if a refart is continuously refarted, causing an infinite refart.
Guy 1: I tried to dutch
oven my
wife last night, but she turned it around on me.
Guy 2: What, did she refart it?
Guy 1: Yeah, right in my
face.
