When all players are aligned in a circle and they play footbag (hacky-sack), a loser lunge occurs when a player kicks the footbag into the middle, without a definite player as the target. What ensues is that one or more players will try to lunge for the hacky sack in the middle and usually miss. All the players that lunged for it and missed will have done a loser lunge.

A loser lunge is an action associated with 'hacky sack' or 'footbag'. This action is expressed when the hacky sack is in an inconvenient place, usually unreachable by the original kicker.

Therefore, someone else, or the original kicker will try to extend his or her leg as far as possible, trying to "lunge" for the hacky sack to keep the play alive.

The saying is derived from how the person who lunged for the hacky sack is usually determined as the loser. It is customary, and acceptable that the other players insult the loser lunger.
