Coffee, slangily
I believe the answer is:
joe
'coffee slangily' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for joe that I've seen before include "- Bloggs; - Public" , "Boy's name" , "-- Bloggs, ordinary man" , "--- Gargery (Great Expectations)" , "-- Orton, playwright" .)
