Bow-legged British man (5)
I believe the answer is:
bandy
'bow-legged' is the definition.
(I've seen this before)
'british man' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'man' becomes 'andy' (I've seen this before).
'b'+'andy'='BANDY'
(Other definitions for bandy that I've seen before include "Bow-legged" , "Curved" , "Bow (legged); swap (angry words)" , "Crooked" .)
