hachel
a person who can be cool to her friends but will make you feel like a f***ing f*** if you don't pay attention to her
She was nice to me until I didn't look at her. Then she called me a f***ing f*** and walked away like I was a ghost.
She was friendly until I didn't laugh at her joke. Then she yelled at me like I was the worst person ever.
She smiled at me until I didn't say hi. Then she gave me the silent treatment like I was a total f***.
