## Definition

to laugh so hard that you cannot stop. You use this when something is extremely funny.

For teachers: to laugh uncontrollably or to cause someone else to do so. Often used in the passive voice or with a reflexive pronoun in informal British English.

## Examples

- That joke really creases me every time I hear it.
- The entire audience started to crease when the comedian's prop accidentally fell apart on stage.
- It is impossible to watch those old home videos without creasing, as the sheer absurdity of our childhood outfits becomes apparent to everyone in the room.

## Pitfalls

- Not "I was creased of the joke" but "I was creased by the joke" — When used in the passive sense to mean 'made to laugh', it takes the preposition 'by' or 'at', not 'of'.

## Usage notes

- Often used in the phrase 'crease up' or 'creasing with laughter'.
