Nicegirl 

The name that's commonly used for a certain girl named Jessica Hall. This does not necessarily mean she is a "nice girl" because of the lack of the space in between "nice" and "girl", and should not be used as in "she's a nice girl", but as in "she's Nicegirl"
It is a proper noun and has been linked with Jessica Hall for almost 3 years.
Given to her by Tyler Gunn and Nate Irvin, and some other guys that were there at the time

Nicegirl- "Hey! I got my tits signed by Dani Filth and partied all weekend!"
Guy- "I thought you were supposed to be a nice girl?"
Some other person- "Retard, her NAME is Nicegirl she's not a nice girl!"

Nice Girl 

A girl who believes she's the best choice for a girlfriend. She doesn't understand why guys only go for "sluts" or "whores" when she can "cook and clean" and also she's "ugly so it's not like I can ever cheat on you!!!!!!" Nice Girls have self-esteem issues and throw passive-aggressive fits on social media when they get rejected. Nice Girls believe that you can tell whether or not a girl has morals by looking at the size of her butt. Nice Girls are self-centered, jealous girls usually in their teenage years, but some occasionally last up until 30s. Others never grow out of their Nice Girl phase.

Nice Girl: "Ugh, why doesn't Brad notice me?! I'm super cute, obsessively loyal, and all I ever do is read books and play video games! I'm not like other girls, I'm special!!!"
Nice Girl: "Stacy is such a slut. I can't believe Luke turned me down for her! Her butt is so big, she probably doesn't even know how to keep her legs closed. Guys are so stupid."
