Guy drinks, from what we hear (5)
I believe the answer is:
tease
'guy' is the definition.
(thesaurus)
'drinks from what we hear' is the wordplay.
'drinks' becomes 'teas' (tea is a kind of drink).
'from what we hear' indicates a 'sounds like' (homophone) clue.
'teas' sounds like 'TEASE'.
(Other definitions for tease that I've seen before include "Rib, wind up" , "Gently rib" , "Irritate playfully" , "Chaff" , "Josh" .)
