in the sport of basketball, whenever a player makes 3 consecutive baskets from down town (3 3pointers) he/she has entered what is known as Heat Check Time. Heat Check Time entitles that specific player to the right of shooting the ball from anywhere and not be called a ball hog.
wow Vince just made 3 threes in a row... "HEAT CHECK TIME". "everyone pass it to him" ... (Vince then continues the streak to 7 in a row because of HEAT CHECK TIME)
A time to test your of will power, courage, fortitude, etc. Rarely does it involve any physical strength or skill, instead being an almost entirely mental challenge. First heard in the US Army, but has spread through usage amongst veterans and wrestling announcers.
when two or more wrestlers have been fighting for a long time, and are both exhausted, its gut check time, to get back into the match.
