Ogre in for chat (3)
I believe the answer is:
orc
'ogre' is the definition.
(both are horrible fantasy creatures)
'in for chat' is the wordplay.
'in' indicates a hidden word.
'ORC' is hidden within 'for chat'.
(Other definitions for orc that I've seen before include "Tolkien's creation" , "Tolkien ogre" , "Tolkien creature" , "Killer whale" , "Mythical monster" .)
