announcer's curse
A state or condition in which an athlete fails to perform a skill that an announcer just praised him or her for. Also known as "announcer's jinx." Can an announcer jinx a player? Who knows? But phenomena like this suggest that consciousness may not in fact entirely reside in the skull cavity. When science develops more fully, we may one day have proof.
Let's say a basketball player is about to make a foul shot. The announcer reports, "She hasn't missed a free throw all night!" The player steps to the line and proceeds to miss the shot. Announcer: "This must have been a case of announcer's curse."
