## Definition

to roll around on the floor while laughing very hard. You use this when something is so funny that you cannot stay standing or sitting.

For teachers: to roll on the floor laughing. An intransitive verb common in digital communication to indicate extreme amusement.

## Examples

- That joke was so funny I almost started to rolf.
- The video of the cat failing to jump onto the counter made everyone in the group chat rolf.
- While the term has largely been superseded by more modern acronyms, it remains a nostalgic marker of early internet culture used to signal uncontrollable laughter.

## Pitfalls

- Not "I am rolfing at the movie." but "I am rolling on the floor laughing at the movie." — In modern English, 'rolf' is almost exclusively used as an acronym (ROFL) or a slang verb in text; using it in spoken formal English may cause confusion with the name 'Rolf' or the therapeutic practice 'Rolfing'.

## Usage notes

- Intransitive verb; does not take a direct object. Often used in lowercase in casual digital contexts.
