Getting hugged and kissed by or having a fat fugly chick with a mullet hang on you because you were once nice to her and now she thinks you 2 are friends. Usually happens in public with a lot of people around (friends and attractive women). If she is drunk this can happen more than one time in a day.
Highly embarrassing for yourself. A great laugh for your friends at your expense.
I was hanging out at the local bar last night and I got mullested by Francine.
To be sexually molested by a person with a mullet. Improper or unwanted sexual advances made by a mullet head.
My boys want to go to the monster truck rally but I'm afraid they might get mullested there.
