fourovertime
Fourovertime is a descriptive term used in sports journalism and fan discussions to denote a game that extends beyond the standard overtime periods and requires four additional overtime periods to determine a winner. The term is not an official rule designation; it is used to convey the length and intensity of the contest.
Common contexts are basketball and ice hockey, where regulation play may be followed by multiple overtime periods
Four-overtime games are relatively rare, but they occur with enough frequency to be notable in narrative coverage.
