An unremarkable, dumpy looking girl or guy. Usually short and round. Typically you will have a friend who is inexplicably attracted to a potato and spend an inordinate amount of time chasing the potato.Usually giving the excuse that she/ he has a great personality or attributes no one else can see
Dude why are you obsessing over this girl, she’s just a potato. No she has an incrediblepersonality.
Potato is what someone says when they try to be random because they are under the belief that by being random they instantly and unarguably become cooler and funnier. This is about as wrong as the entire 2016 election.
