An Exposed Bin

Freddy was visiting a friend the other day. He had some trash that he wanted to throw away, but could not find where the rubbish bin had been placed. So he asked, "Where can I throw this away?" And his friend replied, "Oh, just open the cupboard , it's in there. I don't like having an exposed bin." Freddy, of course, replied, "Is that a euphemism?"
