DafCun
A lazy and flaky version of the full-blown 'Daft Cunt' insult. Only works if you're a bit thick or you're being cheeky. Otherwise, it's just the start of a full-on fight.
'DafCun, I’ve seen you eat a whole cake and still be hungry.'
'DafCun, you’re like a broken toaster.'
'DafCun, you look like you’ve been hit by a bus and a chicken.'
