Partners occupying different beds, pillocks (6)
I believe the answer is:
dweebs
'pillocks' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'partners occupying different beds' is the wordplay.
'partners' becomes 'we' (West and East are partners in the game bridge).
'occupying' is an insertion indicator (inserted letters occupy or enter the word).
'different' is an anagram indicator (letters placed in a different order).
'beds' is an anagram of 'debs'.
'we' placed inside 'debs' is 'DWEEBS'.
Can you help me to learn more?
(Other definitions for dweebs that I've seen before include "nerds" , "They're socially inept!" .)
