Someone who's catty is mean and nasty. A catty student on a school bus might refuse to let another child sit beside him, saying, "You smell bad."

If you act catty, you're malicious or snotty toward other people. The adjective is unfortunately used more often to describe females than males, but anyone who treats people nastily can be called catty. The word was originally cattish, with the same meaning — and earlier, it simply meant "pertaining to cats."
