By all means, dump yes-man from The Globe (4)
I believe the answer is:
ball
'yes-man from the globe' is the definition.
'ball' can be an answer for 'globe' ('ball' can be a synonym of 'globe'). I'm not certain of the 'yes-man from the' bit.
'by all means dump' is the wordplay.
'by' is a charade indicator (letters next to each other).
'means dump' becomes 'b' (I am not sure about this - if you are sure you should believe this answer much more).
'all' after 'b' is 'BALL'.
Can you help me to learn more?
(Other definitions for ball that I've seen before include "Old song: 'After the .... was over'" , "All-round" , "Perhaps a bouncer < 's clog" , "Sphere - dance" , "Social function for dancing" .)
