Male's drivel about runner-up's prize (6,5)

I believe the answer is:

silver medal

I'm a little stuck... Click here to teach me more about this clue!

But I can't explain it at all! Could you help me understand?

(Other definitions for silver medal that I've seen before include "Sporting prize" , "Olympic prize" , "What won't satisfy champion" , "Prize for second place" , "Runner-up award" .)

I've seen this clue in The Mirror.
