twonk

A stupid person.

You dozy little twonk, Rodney. You bang again on the roof of my van like that and it won't be Frankie Goes to Hollywood, it'll be Rodney goes to hospital.

The absolute state of you, Downey, you utter twonk. Like you have anything to do with the outcome of the bloody match! You need to confine this superstition malarkey to a flaming skip.

Nonsense; rubbish.

What twonk you are talking!

To hit or slap.
