Spots some men carelessly falling over (4)
I believe the answer is:
acne
'spots' is the definition.
(I've seen this before)
'some men carelessly falling over' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'over' is a reversal indicator.
'enca' is hidden within 'men carelessly falling'.
'enca' back-to-front is 'ACNE'.
(Other definitions for acne that I've seen before include "Pimply skin condition of adolescence" , "Skin condition associated with pimples" , "Skin disorder" , "Problem to face in" , "Skin spots" .)
