I believe the answer is:

disobeys

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

'rebels' is the definition.
The definition and answer can be both to do with social activities as well as being verbs in their -s form.
Perhaps you can see a link between them that I don't see?

'boys' side prepared' is the wordplay.
'prepared' indicates an anagram.
'boys'+'side'='boysside'
'boysside' is an anagram of 'DISOBEYS'.

'for' acts as a link.

Can you help me to learn more?
