DafCun
A silly and slow version of the full-blown 'Daft Cunt' insult. Only works if you're thick enough to not take it as a massive insult. If you're not, it's the start of a full-blown war.
'DafCun, you’ve got more hair than a goat and more brains than a pigeon.'
'DafCun, I’ve seen you eat a whole pie and still be hungry.'
'DafCun, you look like you’ve been hit by a lorry and a chicken.'
