Question

Is this sentence OK?
(a game etc.)

He can't take losing at all.

Answer

If you want to say that he does not like to lose, I would say:

1) He can't stand losing
2) He hates losing

If you want to say he gets angry or unlikable when he does not win, I would say:

1) He is a poor loser
2) He is a sore loser
3) He's not a good sport
4) He does not have good sportsmanship
