At my gym, we nicknamed the dudes that walk around the locker room naked as "Trollers"
Cause they troll around there all day. Some of them never even leave the locker room...sit there and watch TV and go to the steam room then to the whirlpool.
It's mostly old dudes and I guess I don't expect them to be out on the treadmill running 5 miles....but for christs sake it's not social club. Work out and go home.
I hate trollers.
