A person known as a former friend but now you realize is a bitch and slut who thinks too much about herself and uses everyone as a puppet.

Molly is a very thin person, Molly’s are usually eccentric enough to attract any man, but they mostly attract women as 80% of the time molly is a lesbian. They are sporty, genius and don’t even have to try to be witty or sarcastic to get their point across. Molly’s can go through dark times but mostly are a bubbly, loud person that can get very,very annoying and obnoxious.

Someone who is rather chunky and/or chubby. Not necessarily fat but still rather tank-like. Usually with big thighs.
