look up any word, like the eiffel tower:
 
1.
A person who can be found at the Ritz Bar in Jacksonville Beach on every Friday and Saturday night. This person is usually on a first and last name basis with every bartender, doorman, dj, and fellow ritz rat. It is not an uncommon occurrence to spot a ritz rat popping in on a Sunday afternoon to close out his/her tab that was left open all weekend, if he/she isn't Sunday Fundaying at Lemon Bar. Buy a ritz rat a gatorade and a shot of goldschlager and you'll be invited to hang in his/her world.
slutty hot girl 1: "Ugh! That girl just got a drink in 10 seconds, when I've been waiting for 10 minutes!"

slutty hot girl 2: "She must be a ritz rat."
