bum tan

Getting that unique that no one but a bum can get from sitting in the sun for hours asking for change. Bum tans take about one summer to fully blossom.

A bum tan is generally super leathery and looks similar to what a construction worker's tan.

Have you seen John lately? He's got a sweet bum tan going on.
