I believe the answer is:

flair

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

'talent' is the definition.
(flair is a kind of talent)

'fellow show-off' is the wordplay.
'fellow' becomes 'F' (abbreviation - of a society etc.).
'show-off' becomes 'lair' (I can't explain this - if you can you should believe this answer much more).
'f'+'lair'='FLAIR'

'reveals' acts as a link.

Can you help me to learn more?

(Other definitions for flair that I've seen before include "skill" , "Natural talent and aptitude" , "gift" , "Style, talent" , "Talent; elegance" .)

I've seen this clue in the Sydney Morning Herald.
