vagina trouser 

a cleverly shaped piece of cloth designed to hold the external labia from slapping each other and create the much dreaded "vaginal slapping noise", also referred to as a "snatchsmack" or a "chesterfield". Normally only happens to overweight women because the fat weighs the flaps of skin down. Sometimes vagina trousers are equipped with absorbant material to collect any unwanted drippage.

"That girl over there is emitting chesterfield as noise pollution! She needs a fucking vagina trouser!
