NEW YORK (AP) _ Her name is Muffin, but she's one tough chick.

Muffin Spencer, singer and guitarist for the pop-funk band Brassy, is known for chastising men at her concerts who don't dance.

``There's a notion that if you don't start jumping up and down, Muffin'll give you a mouthful,'' band member Jonny Barrington, also known as DJ Swett, tells Spin magazine in the February edition. ``Men being frightened of her is great. It makes the rest of us look hard as well.''
