The manner of tucking a men's dress or casual shirt such that the front tails are tucked in but the back tails are not. Said purpose for doing so is to keep the front tails from getting chewed up by one's belt buckle, while still affecting a casual air. Most prevalent among hipsters, college undergraduates, and the clueless.
Perhaps the reason Detective Charles "Charlie" Crews Jr. (Damian Lewis), in the TV series Life, sometimes sports the bro tuck is to conceal the service weapon he keeps pushed in the back of his jeans.
