Any group of rich young degenerates; people trying to be cool and failing. Capable of humour so bad it hurts. Arrogant self-loving US males too drunk and stupid to realise they look like jerks. Originally from the famous Frank Sinatra and friends. Any group of young adult US males wearing bad clothes and behaving wierdly.
Look at that fucking US brat pack.

A group of stars who were featured in 80s teen movies. The name comes from a play on the term Rat Pack.
Rob Lowe, Demi Moore, Emilio Estevez, Andrew McCarthy, Ally Sheedy, Anthony Micheal Hall, and Judd Nelson were all members of the Brat Pack.
