Frontman and band get bullsh*t crowds (4)
I believe the answer is:
mobs
'crowds' is the definition.
(I know this)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for mobs that I've seen before include "Unruly crowds" , "riotous assemblies" , "Disorderly crowds of people" .)
