Some Like It Hot man (5)
I believe the answer is:
keith
'man' is the definition.
(I've seen this before)
'some like it hot' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'KEITH' is hidden within 'like it hot'.
(Other definitions for keith that I've seen before include "Man" , "Man's name" , "----- Jarrett, American jazz pianist" , "----- Floyd, TV cook and raconteur" .)
