Term to describe someone as being overtly or even subtly homosexual in mannerisms or the such. Believed to be originated from an Organic Chemistry class taken at the University of Houston when the teacher described proper nomenclature for an organic molecule with a bromine attached to it. Bromo sounded a lot like Homo, and the rest is history.
"John you're such a fucking bromo!!!"
