I thanx nada
A funny and rude way to say no, with a little bit of swearing and a lot of disrespect.
'Can I borrow your shirt?' 'I thanx nada, I'm wearing your face.'
'Do you want to play video games?' 'I thanx nada, I'm beating you at your own game.'
'Can I have a hug?' 'I thanx nada, I'm smothering you to death.'
