Ridicule name for common herd (6)
I believe the answer is:
ragtag
'common herd' is the definition.
('ragtag' can mean a disordered group)
'ridicule name' is the wordplay.
'ridicule' becomes 'rag' (both can mean to tease).
'name' becomes 'tag' (tag can mean a name or label).
'rag'+'tag'='RAGTAG'
'for' acts as a link.
(Other definitions for ragtag that I've seen before include ". . . . . . and bobtail, the rabble" , "Badly organised" , "hoi polloi" , "Disparaging term for the common people" , "Mob" .)
