Scatter drapes around (6)
I believe the answer is:
spread
'scatter' is the definition.
(I know that scatter is a more specific form of the action discharge)
'drapes around' is the wordplay.
'around' indicates an anagram.
'drapes' with letters rearranged gives 'SPREAD'.
(Other definitions for spread that I've seen before include "Unfold - scatter" , "Special display" , "Broadcast" , "Generous meal" , "Type of betting" .)
