knock spots off someone/something
knock spots off someone/somethingBRITISH, INFORMAL
If one thing or person knocks spots off another, the first is much better than the second. I'm looking forward to the return of her chat show. It knocks spots off all the others. Caroline didn't have much experience, but she knocked spots off everyone else I'd interviewed — she was so charming and friendly. Note: The reference here is probably to someone who is shooting so well that they are able to knock out the spots or marks on a playing card that they are aiming at.
