Slumbergate 

A conspiracy in the Dallas Cowboys football organization in which WR Terrel Owens along with fellow WRs (names don't matter) believe that Tony Romo makes special plays with his favorite reciever, and friend, TE Jason Witten in hotel rooms during road trips.

The wide reciever core called a special meeting on December 11 with the offensive coordinator to iron out the issue.

Guy 1: "Have you heard about Slumbergate?"

Guy 2: "Yeah. I think TO is just bitchin'."
