A Thandi
A Thandi is a guy who thinks he can pull off a wank in the middle of his day like it's no big deal, but when he's supposed to be with his friends, he'll drag things out until people are ready to punch him.
Thandi: 'I'll be there in 10 minutes.' (He shows up 3 hours later.)
Thandi: 'I'm just gonna take a quick leak.' (He's still there at midnight.)
