A kip is a quick sleep or a proper snooze, usually unplanned, like you’ve slumped on the sofa after work. Saying you’re having a kip just means grabbing some shut-eye, not moving house. It’s an older British bit of slang, linked to the idea of a cheap lodging place, and it’s still used everywhere.
"I’m gonna have a kip on the sofa, yeah. Wake me at eight or I’ll miss pre-drinks and end up rocking yesterday’s jeans again."
