Another male full of hot air (7)
I believe the answer is:
thermal
'hot air' is the definition.
(thesaurus)
'another male full of' is the wordplay.
'full of' says the answer is hidden in the clue (inside).
'THERMAL' is hidden within 'another male'.
(Other definitions for thermal that I've seen before include "Concerned with high temperature" , "Warm or hot, say air or spring" , "Relating to heat" , "Pertaining to heat" , "help for glider" .)
