Basically, via the urban definition of the term - clutch refers to a person or team being able to perform under pressure at the critical juncture of a game or competition.
To mix my metaphors (hold the ice), it means that at the "crux of the matter", the best of us will be revealed as "clutch".
Others describe this trait as being able to deliver exactly what you need, exactly when you need it - being derived from the clutch mechanism in a manual car where perfect timing means the difference between a launch and a stall.
I drive an auto these days, but I think that statement likewise rings true.
So, who has been clutch and who has been not clutch in the world of sport in the past week?
CLUTCH
The Iceland football team at Euro 2016 is totally clutch, as evidenced by their slaying of the Three Lions on Tuesday.
Their co-coach is a part-time dentist, their team is selected from a population of only 333,000, and it's too cold up there to have their own professional domestic league.
But in front of nearly an eighth of their own population at France's Allianz Riviera, Iceland put down a shellshocked England team who if you floated them on the world-wide market would have a Dow Jones rating of several hundred million more than the boys that vanquished them.
Perhaps the best part has been listening to the high-pitched and utterly magnificent meltdown of the Iceland television commentator Gudmundur Benediktsson - screaming himself hoarse like a 14-year-girl at a Justin Bieber concert.
"You can leave Europe! You can go wherever the hell you want!" Benediktsson exulted at the English team at fulltime. Had he been American, perhaps one word would surfice - "clutch".
Not Clutch
Serbian Viktor Troicki is not the type to be able to quickly readjust and put the last tennis serve behind him while he prepares for the next.
After umpire Damiano Torella made an over-ruling of a ball being out in the final set of his round two Wimbledon match with Spain's Albert Ramos-Vinolas, Troicki well and truly flipped his lid.
Snatching the ball from a terrified-looking teenaged attendant, Troicki stormed up to Torella demanding he tell him where the chalk from the line was.
"No way, look at it," the 27th seed ranted, before removing the prospect of more serious inspection by smashing it out of Court 17 and into the All England Club grounds.
Losing the match on the following serve, Troicki kept it up right at Torella's feet.
"Do you know what you did?" he screamed three times, when once would have sufficed - heck, the tourists walking up the Tower of London steps could have heard him.
Not only is Troicki not clutch, but someone needs an nice cup of chill-the-heck-out.
I think there's a couple of likely candidates for each term.
Feel free to dive into your own sports watching this weekend to see who can deliver clutch and who is so totally not clutch.
