What is Knob-chops?
1.
A bit of a muppet, who no-one really likes, but you just put up with because you can laugh at him when he thinks you are laughing with him when he tells a(nother bad) joke.
"That Tom, he's a right knob-chops. Bad jokes and even worse back-hair, but a least you'll be able to have a laugh."
