Noun; Derogatory/Insulting term to describe a extremely pale girl. Preferably one who is ginger or has lots of freckles. Comes from the fact milk is white, and girls have piss flaps.
See Nicole Kidman for a text book example of milk flaps
A pocket or fold of skin on a baby'sneck, under the chin, that collects dribbled milk from the bottle or nipple, and remains trapped. The milk begins to go rotten and cause your child to stink horribly. When you give the child a bath or shower, you will notice brown sludge hidden away in the milkflap.
Husband: I am giving the baby a bath OK?
Wife: OK, but make sure you wash that stinking milkflap, it's getting pretty rank!
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."
