Slang for a very beautiful girl, someone having calmness of that of a mermaid sitting on a rock in a turbulent sea and smiling. Also used for a girl who is vulnerable and innocent as dove
She is a beautiful girl, a Mermi.

A mermis is someone who likes it in the ass. he not only likes it in the ass, but he likes it when people pull the good old toasty bustier on him.
