“That new comedy is great. You should definitely see it. You’ll die laughing!” 「新しい喜劇がすごく面白いよ。絶対観るべき。笑いすぎて死ぬよ!」


Don’t worry, you won’t actually die. You’ll just laugh very hard for a long time. There may be some examples of people literally dying while laughing in history, but the phrase usually just means something is very funny.
