A female counter part of a Bro. Native to college campuses, Dave Matthews band concerts and tail gates. Often wears sorority t-shirts, North Face fleece jackets and especially Tiffany an Co. bracelets, for which they are named.
Tell-Tale signs of Tiff behavior include but are not limited to: Showing die hard support of a sports team in order to attract attention from Bros, Beer Pong, Flippy Cup, Making T-shirts for minuscule events, wearing Pink pajama pants and fleece to class, painting celebratory messages on the windows of friend's vehicles using car paint.
I almost got hit on the way to class by some Tiff who was too blasting Lady Gaga out of their Jeep Wrangler to pay attention to the road.
