I personally feel the word ‘Brexit’ should be used as a term referring to an absolute thicket in the same way as ’he’s a total head-the-ball’ etc. Having it used in that way in common parlance would hammer home the absolute idiocy of the whole idea altogether.
’Here comes Tony, he’s a proper Brexit’
‘fucks sake, I totally brexited that up’
Waiter drops a tray of glasses everyone in the restaurant shouts ‘Brexit’!'
