apres-ski

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

'entertainment on the slopes' is the definition.
'apres ski' can be an answer for 'entertainment' (I've seen this before). I am not sure about the 'on the slopes' bit.

'regularly talk big about journalists'' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'about' indicates putting letters inside.
'journalists'' becomes 'press' (the press can mean the newspaper industry).
'talk'+'big'='talkbig'
The alternate letters of 'talkbig' are 'aki'.
'aki' enclosing 'press' is 'APRES-SKI'.
