Can't touch this!
Cheers!

A word used by Britons on any occasion, covering any meaning from 'thanks', 'hello', 'no problem', to 'an alien just raped your chinchilla in the left corner of my blue garden shed'. Usually followed by the term 'mate', which is also 100% devoid of semantic content and meaning. This phenomenon is taken by some continental scholars as strong evidence that all Britons are telepathic.
