The definition is at the beginning of the clue.
How the clue works
Right, so mean is your definition — think "what are you getting at". For the wordplay, "for one" gives you EG (as in "e.g."), and that gets reversed ("to return") to become GE. Stick TAT ("rubbish") on the end of that and you've got GE followed by TAT, giving you the answer.
