Here is how that ref would describe a false start penalty to the crowd "The offensive lineman, number 69, moved too early, well before the ball was snapped from the Center to the QB. This is especially bad because it can draw the defense offsides. Therefore, this play has been called dead, and the offense will be penalized with a loss of 5 yards from the previous line of scrimmage. It is still first down, which means that there will be up to 4 more opportunities for the offense to reach the 15 yards required to make a first down. The clock will remain the game and both teams will maintain the same number of timeouts as before this penalty."
