What does the word clutch mean in basketball?

[Nikki]

I was on twitter while the game was on and people kept saying things like

Heat fans: "lebron is clutch"

Non heat fans:"lebron is not clutch"

[Mr Rondoâ„¢]

Refs

[Jeff]

When they go all out

[chig]

consistency making shots in the last 2 mines of the game (clutch time)

[wintergreen]

its when you're able to make shots when it's most needed, when there's the most pressure. for ex if the game's tied and you score in the last 5 secs of the game, you're clutch

[Cody]

It means when the game is almost over and it's close and the pressure is on you can count on him to make the shot to win the game

[BlackMamba]

when lebron travels but the refs pretend to look the other way

[Qwerty]

clutch- is when you make big plays with the game on the line to win the game
