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.
