In basketball, "hangtime" refers to the amount of time a player stays in the air after jumping. It is a measure of a player's jumping ability and is often used to describe a player's athleticism or ability to make spectacular plays, such as a slam dunk. A player with a high hangtime can stay in the air longer, which can give them more time to make a shot or execute a move. It is not an official statistic but it is something that fans and commentators often use to describe a player's jumping ability.
