GBM 

Gay black male (or alternately gay black man). GBM is not a pejorative and is used matter-of-factly.

This GBM in my English class does the best Rick James impersonations.

Gay Black Man or Gay Black Male. Not an insult - just a code word.

GBM 

An acronym for "Generic Business Men". Used to refer to the ubiquitous suit-and-tie sort that crowds restaurants around noon during the work week. Often travelling in groups, these creatures are easily identified by their nearly identical work uniforms, boisterous but insincere laughs, and alcohol breath.

"The Tavern was full of GBMs so went to ate at BJs Brewery"

"Gay Bar Mike"

This is the name you give a friend who tends to do gay things whether it is going to gay clubs when he is straight or just dressing like a fag.

"Hey guys, lets go to a gay bar i hear thats where all the ladies hang these days."

"Man you are such a GBM"
