Student on the phone to his mum;
Son: 'Mum, I can't afford to wash my clothes so I just wear the same ones over and over again'
Mum: 'God! Your such a duber'
'Man, did you just lick your plate and put it back in your cupboard? Your such a duber'
'DON'T DRINK FROM THE MILK BOTTLE! Your such a duber'
"Yeah, I broke up with him yesterday."
"How did he take it?"
"That Duber keyed my car and shat on my doorstep!"
