## Definition

to kiss or have a sexual encounter with someone you just met, usually at a party or club.

For teachers: to engage in sexual activity, ranging from kissing to intercourse, typically with a casual acquaintance or stranger; highly informal British slang.

## Examples

- Did you cop off with anyone at the party last night?
- He spent the whole evening trying to cop off with the girl he met at the bar.
- The film depicts a group of teenagers desperately attempting to cop off with their classmates during a chaotic summer music festival.

## Pitfalls

- Not "He copped off her." but "He copped off with her." — the preposition 'with' is necessary when mentioning the person involved.

## Usage notes

- usually followed by the preposition 'with' and a person; very informal and primarily used in British English.
- Teaching tip: this is a slang term that may be considered crude or dated depending on the region; contrast with 'hook up' which is more common in American English.
