hasselhoff /HA sel hof/ [size=92]verb, intransitive[/size]
to slip and fall down badly while shaving or (more broadly) in the bathroom
The term comes from a surname of a celebrity whose unfortunate accident resulted in many comments on the internet. It is not clear, however, where and who used it first.
Just don’t hasselhoff!
God, what happened to you? I hasselhoffed.
