Another word for a hoe, slut, whore, etc.

A girl is referred to as a penny because like a penny, that girl is damn near worthless. She is used because she's convenient, but no one really likes her. She can be found in everybody's pants.

1. You are two faced (meaning you hang out with someone then you go talk crap about them to another friend) and in everyone's pants, so if you are looking it up because someone called you that, then they were either insulting you or, well there is no or, they just don't like you. :)

2. It is also one of those little brown things that have Abraham Lincoln's head on it and are worth 1 cent, but if you live in America and don't know that GTFO.
1. Man, I thought Sky was my best friend, then she started talking crap about me to Jimmy, She's just a two-faced lying jerk.

Penny is a girls name and is sometimes used by drag queens. Pennys are typically angry and have strong opinions. They think they’re much smarter than they actually are. They prefer to be really tan and ignore skin cancer warnings. Pennys drink a lot and most of the time end up face first on the sidewalk. Teacher is their preferred profession as they like to spread their mean bigoted opinions on to our youth. If you know a penny, you’ll constantly have to worry about offending their delicate Constitution.
Even though my friend Penny is named after money, she never has any.
