kwebber

The corridor cleaning machines with circular furry discs on the underside.

This name is unique to my school. It's not a dialect thing. Shut up and let me explain. As a group of us sixth formers were engaged in some light vandalism in the common room, the head caretaker walked in and caught us.

Angry, but not having enough respect or guts to challenge us directly, he said "stop that, or I'll go and get Mike Webber". The idea of our Deputy Head, Mr Webber, having an informal first name didn't register, so there was a moment of confusion before someone asked "what's a kwebber?"

The only thing that made sense was that he was offering to tidy up our mess with his massive sandy-wheeled machine. So on we carried.
