An extremely large (if not totally obese) goth person.
The fattest goth you've ever seen.
A morbidly obese person who tries to secure a position in a social group by picking the most outcast group they can think of; this last few years that's been the goths.
Dressed as such merely for the advantage of "fitting in" with another set of people other than the rest of the hippos.
Shay is such a friggin' gothapotamus! I wish she would just put down the twinkies & take shower. I sooooo don't want to try to outrun the police in a graveyard with her!
