TBM =
Temporary Blond Moment
Doing or saying
something so incredibly dense, people
look at you to make certain you aren't blond.
AKA a "Here's Your Sign" moment.
Examples of a TBM:
Asking the ticket counter agent "What time does the 5:15 redeye to Chicago leave?" when the flight schedule is right behind you on a big screen.
with 20 seconds left in the 2013 NFC Divisional Championships,
New Orleans Saints wide reciever Marques Colston receives a pass from Drew Brees; instead of stepping a half-foot
to the right and going out of bounds to stop the clock and give the Saints a chance to win the game he turns to his left and tries to lateral to teammate
Darren Sproles. His pass goes forward instead of lateral, and the illegal forward pass penalty loses the game for the Saints.
