I believe the answer is:

punch

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

This could be a double definition.

'the kiddies may think him' is the first definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.

'a knockout' is the second definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps there's a link between them I don't understand?

Can you help me to learn more?

(Other definitions for punch that I've seen before include "Poke" , "Thump" , "Strike with fist" , "Strike, Judy's husband" , "Blow with the fist" .)
