What does the term "simultaneous with the snap" refer to?

The term "simultaneous with the snap" specifically refers to actions that become fouls at the moment the ball is snapped to begin the play. In the context of football rules, this means that certain infractions are not considered fouls until the ball is put into play, making the timing of the snap critical for determining whether an act is a violation. Understanding this term is essential because it highlights the distinction between actions that are permissible before the snap versus those that result in a penalty once the play has officially started. This clarity is important for players, coaches, and officials in interpreting the rules and maintaining the flow of the game.
