A girl that isn't the same as all the other gils. She is known for her beauty not only on the out, but on the in. One of those girls that every girl wants to be and a girl that every guy wants to be with. Stylish, fun, loving, truthful, beautiful, and sincere.
Guy 1 : She is so perfect. But I thought her name was Hillary?

Guy 2 : No, Hilari! Hillary is a total opposite.

Guy 1 : Oh, damn! That explains it. I gotta get with that.

Hilary is a girl who is quiet. When you actually get to know her she's very loud and could be your best friend. She is the best friend ever ok. Just don't get on her bad side or else you'll get your ass kicked by her. Also, she's very um not lazy like me and does her homework before me and I always do it the day before it's due. *COUGH* she likes to play games and her best of best friends is ME AMY!!!! ok bye.
Hilary is that bitch you would want to be friends with.
