A hunk messed around with a wiseman (6)

I believe the answer is:

kahuna

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

'wiseman' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'a hunk messed around with a' is the wordplay.
'messed around with' indicates an anagram (I've seen 'messing around' mean this).
'a'+'hunk'='ahunk'
'ahunk' anagrammed with 'a' makes 'KAHUNA'.

Can you help me to learn more?

I've seen this clue in The Guardian.
