Hang time

In American football, hang time (or hangtime) is the amount of time between when a ball is punted and when it is either caught or hits the ground. A punt with lots of hang time might be better than another slightly longer punt that has less hang time, because the one with good hang time gives the coverage team a chance to get downfield and minimize the return, and perhaps even force a fair catch.

In basketball, hang time can refer to the amount of time a player hangs on to the rim after a slam dunk.
