What is 10 Minutes?
What a dealer says when he has left you waiting for weed for up to 3 hours then you ring to enquire on his whereabouts and proposed time scales. Usually this figure is wrong and it will take up to another 30 minutes or another phone call. The dealer will then apologise for this and you just have to accept it as he is selling you weed and if you piss him off then no weed for you and a wasted night.
You "How long are you gonna be mate?"
Dealer "10 minutes. I'm not far from there now."
30 minutes later
Dealer "sorry about the wait...how much you want?"
