Nun is like "fool" or "idiot" but ruder. You can say it at the dinner
table without being told off though, it's not that bad. Everyone can say Nun, except Nuns. Nuns cannot call Nuns Nuns, just as you cannot call a Nun a Nun, otherwise
people will just go; "yeah, thanks for stating the obvious
mate."
1)Egon: "Yo Sam!"
Sam: "Go away you Nun."
2)Sam: "Oi, Daniel, pass the
pepper corns."
*Daniel drops the
pepper corns*
Sam: "Oh you prick, I wanted to eat those pepper corns, your such a Nun."
Daniel: "Don't be so mean, it was an accident."
Sam: "NUN!"
3) Townie in the street: "I fucked yo mama!"
Sam: "Your
mum's a Nun."
