Ritz

A 'Ritz' is someone who is flakey, has tickets on themselves and is generally inferior.

The origin of this insult comes from the American cracker 'Ritz', which attempted to overtake Jatz as Australia's base biscuit of choice. Due to the inferiority of it's taste, texture and transportability Ritz will never beat Jatz, or Savoy if you're from Victoria.

Guy 1: Jimmy is such a fucking Ritz.

Guy 2: Why?

Guy 1: He said he'd pick me up on the way to the pub and he just never showed up.

Guy 2: Classic ritz, always breaking and disappointing.
