stain

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

'shame' is the definition.
(a moral stain)

'fellow hiding current' is the wordplay.
'fellow hiding' becomes 'sta' (I can't justify this - if you can you should give a lot more credence to this answer).
'current' becomes 'in' ('in' can mean current or trendy).
'sta'+'in'='STAIN'

Can you help me to learn more?

(Other definitions for stain that I've seen before include "Satin (anag.)" , "Discolouring mark" , "Discoloured patch" , "Tarnish" , "Smear" .)

I've seen this clue in The Times.
