A "mean omelette" is when a man farts into his girlfriend's vagina (being a fan of the ass to vag fetish), and then later, unintentionally, the lady queefs into said man's mouth during cunnilingus resulting in much disgust.
"She did what into your what???"
"Dude, I got a fucking BEAN OMELETTE!"
"Fuck dude.. I guess I did.. what a bitch!"
