Nasty is an amalgamated word that stands for '
Tasty Knacker'
The term is used to describe good looking men who are easy to
catch but must be disposed of quickly due to their liabilities.
A nasty should be treated with caution and only indulged on in controlled conditions.
Oh, would you look at the nasty coming up the road, should I risk it?

hot, I can't bring myself to send him away.
Laura pulled a total nasty last week, fair
play to her, she got rid of him quick as well.
