The 'Fakenger' thing

photoben Don't know if this is relevant, but 'bout a month ago I was walking past the tate modern with a friend and my fix, saw two Eastern European couriers chatting. Eying up their machines, I said "nice bikes". They replied "yours is shit". That wasn't very nice so I shouted "your mum was shit" and carried on walking...

How do you know for sure.. with their accents they could've said "your bike is the fscking bomb dude!!! Where can I get one like that?!?!?"
