Fellow wearing sleek ruff incited ructions (10)

'incited ructions' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'fellow wearing sleek ruff' is the wordplay.
I cannot quite see how this works, but
'fellow' could be 'les' (Les is a man's name) and 'les' is located in the answer.
an anagram of 'ruff' is 'rfuf' which is within the answer.
The remaining letters 'kef' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
