Boy, some like it hot! (5)

I believe the answer is:

keith

'boy' is the definition.

'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' can be found hidden inside 'like it hot'.

(Other definitions for keith that I've seen before include "Man's name" , "----- Jarrett, American jazz pianist" , "Man" , "----- Floyd, TV cook and raconteur" .)

I've seen this clue in The Independent.
