When someone says something totally stupid. And the magnitude of what they said was so ignorant and idiotic that you are forced to walk away in disgust. That, is when you call them nasty.

Terrence: Oh snap, which Italy team?
Josue: Wow, Terrence you're nasty.

Get the Nastymug. 
Most males are nasty by a females definition of nasty. So unless by calling a male nasty she means he's beyond the realm of nastiness most males are in, calling a guy nasty is like calling somebody that already knows they're an asshole an asshole.

Get the Nastymug. "Nasties" was a term coined in the United Kingdom in the 1980s that originally applied to a number of films distributed on video cassette that were criticized for their violent content by various religious organizations.
There was little rhyme or reason behind these seizures, movies were taken from video shops in one county that were left on the shelf in adjacent counties. Alongside those movies that would eventually be identified as the nasties.
