bro tan

The tan a bro gets after wearing a tank top/bro tank in the sun for an extended period of time. The best 'bro tan' will make a bro look like he is wearing a light tank top with nipples when he is, in fact, shirtless.

"The chicks digged my bro tank so I wore it all Coachella, now I have an epic bro tan!"
