Flag football is a game that is similar to regular football but without the tackling. Instead of tackling, you pull a player's flag off of their belt or waistband. You wear a belt or waistband with flags on it that represent you being "tackled." The goal of the game is still to score touchdowns by advancing the ball down the field, but you do it without getting tackled. It's a fun way to play football if you don't want to get hurt, and it's a good way to learn the basics of the game.
