Stink Bro

A straight-acting DL bisexual guy who spends a lot of time at the gym to get his gains. Usually has a girlfriend, but also has sex with his workout buddy. He uses the gym as an excuse to get sweaty with his stink bro.

I always see Steve and Travis work out together. Would they even lift if one didn't show up?
Nah, man. They're stink bros. They go at it after they lift.
