I guessed they were selling their bottoms.

What is that supposed to mean?

There's a big market in illegal bottom transplants. I myself made my first
million by replacing my own youthful hind with Bernard Manning's cast off.

I'm not talking about a gang here. I'm talking about half a dozen youngish
men, not teenagers - different races, all very poor looking, not talking to
each other or hanging together, just all choosing to loiter in the same back
street. Logically they were either customers waiting for a supplier or
suppliers waiting for a customer.
