Brett calls the team "The Brett Pack" in reference to "The Brat Pack", a group of young actors who frequently appeared together in teen-oriented coming-of-age films in the 1980s. The members of the Brat Pack are generally defined as the core cast members of St. Elmo's Fire (1985) or The Breakfast Club (1985) - namely Emilio Estevez, Anthony Michael Hall, Rob Lowe, Andrew McCarthy, Demi Moore, Judd Nelson, Molly Ringwald, and Ally Sheedy, although other actors such as Robert Downey Jr., Charlie Sheen, Kiefer Sutherland and even Tom Cruise are often included.
"The Brat Pack" itself was a term modelled after "The Rat Pack", a group of famous entertainers, including Frank Sinatra, Dean Martin, Sammy Davis Jr., and others, which existed in 1950's and 60's and occasionally re-emerged until the 80's.
