a woman that looks like a man with man-boobs
ur mothers a right gompa!
Obscure insult of dubious origin, recently given a crass crowbar back into public use in a tragically ill-scripted advert for Bisto Gravy.
Conceivably made up by a PR exec with too much time on his hands, hoping to get some kudos for starting a new trend.
You know that tedious 'mate' you have who thought it would be cool to try and coin a new word by overusing it constantly, despite it having utterly no meaning and sounding ridiculous? He's a gompa!
