A man who is completely lost in life after gettingbout of the security of high school, and has no idea how to define himself or fund meaning in life other than repeatedly lifting weights and taking steroids to get as enormous and humanly possible. They usually base their entire lives aroubd this only wearing clothes that either show off their deformed bodies or say things like "seriously strong"
Tom: How's Tony been doing John
John: Not too well. Poor guy never had any idea what to do with himself, so he's just become a total gym buff. Never does anything but pump iron and dope up until he looks like a human terd.

Get the Gym buff mug.
A guy who spends every spare moment in the gym.
I went over to my ex-girlfriend's house to see if we could patch things up. But, she already had another dude over there, some "Gym Me Buff It" guy.
