Reportedly mock drinks (4)
I believe the answer is:
teas
'drinks' is the definition.
(tea is a kind of drink)
'reportedly mock' is the wordplay.
'reportedly' shows a homophone (sound like).
'mock' becomes 'tease' (teasing is a kind of mocking).
'tease' sounds like 'TEAS'.
(Other definitions for teas that I've seen before include "Hot drinks" , "Beverage made by steeping leaves in water" , "Beverages from leaves" , "Afternoon meals" .)
