Mugs to pass around? (4)
I believe the answer is:
saps
'mugs' is the definition.
(I've seen this before)
'pass around?' is the wordplay.
'around?' indicates an anagram (I've seen 'around' mean this).
'pass' with letters rearranged gives 'SAPS'.
'to' is the link.
(Other definitions for saps that I've seen before include "Weakens, deprives of energy" , "Coshes" , "Weakens, undermines" , "Pass around foolish people" , "Enervates in spas" .)
