a gwyneth
A Gwyneth is someone who eats like it's her job; she likes food, and she likes it a lot; she’s also a total drama queen who will break up with you over a sandwich.
She eats 10 sandwiches in one day and calls it 'a detox.'
She breaks up with you because you didn’t like her 'signature sandwich.'
She says 'I’m not a drama queen, I’m just a sandwich queen.'
