Some love he-men, totally fierce (8)
I believe the answer is:
vehement
'fierce' is the definition.
('vehement' can be a synonym of 'fierce')
'some love he-men totally' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'VEHEMENT' is hidden in the letters of 'love he men totally'.
(Other definitions for vehement that I've seen before include "Ardently forceful" , "Of speech, intense and forceful" , "Showing strong feeling, impassioned" , "Emphatic, intense" , "Irish symbol" .)
