look up any word, like slope:
the measure to which a skirt is judged to be too short. you have a thumbs up and measure the bottom of the skirt against your wrist. if the thumb gets wet (touches poon) the skirt is too short.
man check out the skirts of those ladies. they would totally fail a thumb check.
