A Brunner is a person who resembles Ms. Piggy, Because she is fat, and complains non-stop. Also can be summerized up as Jaba the hut for looks and personality. she is cocky and thinks she is better than anyone. Also someone who cant get any action so relies on taking advantage of drunk guys to get laid. they are generally whores.
Hey look, that Katie is such a Brunner, LETS KILL HER!
