I believe the answer is:

fluke

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

'bit of luck' is the definition.
'fluke' can be an answer for 'luck' (fluke is a kind of luck). I'm not certain of the 'bit of' bit.

'a fatheaded fellow' is the wordplay.
I cannot quite understand how this works, but
'fellow' could be 'f' (abbreviation - of a society etc.) and 'f' is found within the answer.
The remaining letters 'luke' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

'for' acts as a link.

Can you help me to learn more?

(Other definitions for fluke that I've seen before include "flounder" , "One lucky" , "Chance happening" , "parasitic worm!" , "Parasitic flatworm" .)
