I’m cool? The opposite, if not PC! (6)
I believe the answer is:
hepcat
'i'm cool?' is the definition.
(a hepcat is a cool or stylish person)
'opposite if not pc' is the wordplay.
I cannot really understand how this works, but
'pc' is within the answer.
The remaining letters 'heat' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'the' is the link.
Can you help me to learn more?
(Other definitions for hepcat that I've seen before include "Old jazz fan" , "trendy no longer" , "one with it" , "Jazz or swing fan (1940s' slang)" .)
