Top Definition
A highly offesive term used to describe your lesbian sister who hooks up with all the hot chicks you were trying slam. This is not your favorite sibling. Fucks with one's pride.
You think that the hot bicurious chick at the party would be a fun hook-up. Then your aggressive faggot sister intercepts and fucks it up for you.
