Bad boy? (3)

There are a few possibilities for this:

tsk ima

yob

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

'bad boy?' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'bad boy?' is the wordplay.
'bad' indicates an anagram.
'boy' with letters rearranged gives 'YOB'.

Can you help me to learn more?

(Other definitions for yob that I've seen before include "Lout or hooligan, backward boy" , "Troublemaker" , "Thug" , "Tough" , "Hooligan kind of boy" .)

I've seen this clue in the Evening Standard and the King Feature Syndicate.
