One who thinks he or she is a tank when drinking (When he or she is not) then they think they are very cool, when there are not. They disrespect women and do not know how to pleasure them because they turn gay and smell funny and they hook up with people from a different race.
Dude stop you have only had threebeers your being a Macnasty.
An absolute uberbitch. Usually a bitter woman approaching middle age that is angry because she has never had a good orgasm. Or she is bitter because she was unknowingly recorded having anal sex with the hired help. Yeah, that chick. Can sometimes be a college age girl who believes she is hotter than the sun and therefore the world should kiss her ass.
That chick is such a Cunty McNasty, who gave her a swirly while taking her from behind?
