A tiny witch that lives inside the scrotum and bewitches the testicles to burn and cause constant boners and horniness. The nuthag is contagious only through gay sex and sex with fat girls. A nuthag can also be that girl who hangs around with all of her boyfriend's friends instead of her own or a piece of shit asshole.
I think I caught a nuthag from that fat chick. I have had a huge boner for a week and my balls are on fire like a sun-burnt elephant cock....That bitch.
