grabby granny

An older female, usually recently divorced or widowed, who has re-ignited a social life. Grabby grannys tend to think that once they have found their social life again they instantly revert back to the body of their teenage years, and thus dress like they're teenagers. They are overly touchy-feely toward men usually half their age. An ugly cougar.
