A JeNasty is a very unique breed of girl that was raised with a lot of male influence; somewhat like a tomboy but still amazingly sexy and feminine. A JeNasty will say things that shock you, mortify you, and embarrass you. A JeNasty will most likely be stronger than your average girl and can most likely kick your boyfriend's ass. JeNasty's make really good friends and they are handy to have around for parties.
