A more subtle way to say bitch. If two people know what the word means and one does not, the two people can rate how bitchy the other person is without the person knowing what they were rating.
Frank: "Scale of one to ten,how much of a vech is Caroline?
Adrienne: "I'd give it an eleven."
Caroline: "What are you guys talking about?"
A vech is a title for a person that can be used in any situation. For example, it can be used to describe someone who is complaining, bitchy, annoying, boring, etc.
It is one of those words that you can label absolutely anyone with. It can be offensive or funny, light hearted or derogatory.
