Unkind expelling European people in general (3)
I believe the answer is:
man
'people in general' is the definition.
(can refer to humanity as a whole)
'unkind expelling european' is the wordplay.
'unkind' becomes 'mean' (I've seen this before).
'expelling' suggests deleting specific letters.
'european' becomes 'e' (abbreviation e.g. EU).
'mean' with 'e' taken away is 'MAN'.
(Other definitions for man that I've seen before include "Geezer" , "-- Friday" , "us?" , "Adult human male" , "Valet" .)
