A phrase exclaimed when spotting a woman in a bikini or tight-fighting pants who has a particularly noticeable thigh gap--the space between her inner thighs, directly below her pussy.
Thigh gaps are measured in male fingers, as in the number of fingers you could fit into the thigh gap. "Mind the gap" exclamations should be reserved for thigh-gaps of no fewer than four or five fingers.
Thigh gaps of this severity mostly happen to anorexics or girls whose thighs have been freakishly separated from being ploughed.
The phrase itself is derived from an announcement stated over the PA's on the London tubes (subway), which says in full "Mind the gap between the train and the platform."
-Mind the gap! Megan Fox's thighs are so fucking sexy.
What you think when you see those hot chicks in bikinis where their thighs don't touch just below the crotch area.
At the beach with your friends...
-Holy shit! that chick is hot! and check it out "Mind the gap"!
-...yea...(takes mental picture)
Famous phrase that is said at the London Underground warning people who use the subway to be wary of the gap between the train and the platform. It has become synonomous with the London Underground and is repeated several times by stupid, annoying, American tourists who find the phrase fascinating and funny.
