How it's used
This expression vividly describes a reaction to something exceptionally funny, literally suggesting that one's mouth is about to burst from the intensity of laughter. It is highly informal and typically used in casual conversation or when describing online content that is particularly amusing. It carries a much stronger emphasis than simply saying 好笑.
Examples
The joke he told was genuinely hilarious.

Common mistake
Avoid using this in formal or professional settings, as it is strictly colloquial slang. It is also an intransitive verb phrase, so do not try to use it as a direct adjective to describe a person or a joke; instead, use it to describe the action of laughing.
