when a girl ties her hair to your dick and then headbangs which causes her to jerk you off.
my girl gave me a madusa last night.

Get the madusa mug.
A girl who is solely a seductress, she will tempt men to the point of highest seduction, but she will never be able to make up her mind and therefore will never settle down.

If you break a madusa's heart, you will be sorry.
"She is the baddest chick I've ever seen, but watch out man, she's a Madusa."
