When one flips up the collar to the upright position on their polo shirt. From the arabic: popaeus collarus meaning flamboyantly gay. Usually the collar is popped on decidedly feminine pink polos with little alligators on the front. Usually worn by frat bros or UVA students who think they are pimpin', but really look outwardly gay.
