A girl whose belly fat hangs out from her 'to tight button holding on for dear life' jeans... resembling the villians in Super Mario Brothers.
The goonba mainly hangs out at smelly suburban night clubs consuming copius amounts of Jaeger Bombs, dark imported beers, and chicken wings.
I could not see the band playing because all the goonbas were blocking my view with their fat.
Someone who possesses simultaneously the qualities of a goon (i.e. ridiculous, stupid behavior and annoying tendencies) and those of a Goomba (easy to step all over, small and kind of annoying)
What a goonba. I hate that kid.
