Seen my medley? They always applaud (3-3)
I believe the answer is:
yes-men
'they always applaud' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'seen my medley?' is the wordplay.
'medley?' indicates an anagram (I've seen 'medley' mean this).
'seen'+'my'='seenmy'
'seenmy' with letters rearranged gives 'YES-MEN'.
Can you help me to learn more?
(Other definitions for yes-men that I've seen before include "Sycophants" , "lackeys" , "Toadies" .)
