A manqueef is one of those sneaky farts that gets trapped in a dudes butt rack, and travels out underneath the balls, usually happens when sitting/laying in certain positions.
"I was trying not to fart, but I ended up letting out a manqueef instead."
when you have a fart that doesnt have enough pressure to expel itself out from between your ass cheeks and you are forced to squeeze your ass cheeks together and cause the trapped fart bubble to expel from under your ball sack. usually results in a high pitched popping sound
another term for a station wagon, mini-van, or any other kind of vehicle that is targeted at the "family" demographic(also M.A.V.)
"Tactical advantages aside, the M.A.V. is top of the line for the holy warrior troop transport manufactured by the Church of Latter Day Saints Military Industrial Complex. Also great for family trips...to heathen lands."
