An noun referring to a stereotype of a girl (usually 20s-30s, but sometimes your occasional cougar) in today's culture. She is a train wreck and does nothing but spend lots of money, tan, and get drunk at exclusive clubs and cause train wrecks. This word originates from the cast member of Bravo's The Real Housewives of Atlanta, Kim. A one hit one she produced is called "Tardy for the Party", which is where this noun derives from because she is in fact a total train wreck and portrays this stereotype very well.
