Bachelor party I held in our room (7)
I believe the answer is:
boudoir
'room' is the definition.
(boudoir is a kind of room)
'bachelor party i held in our' is the wordplay.
'bachelor' becomes 'b' (abbreviation e.g. BA=Bachelor of Arts).
'party' becomes 'do' (do is a kind of party).
'held in' is an insertion indicator.
'do'+'i'='doi'
'doi' put within 'our' is 'oudoir'.
'b'+'oudoir'='BOUDOIR'
(Other definitions for boudoir that I've seen before include "Lady's chamber" , "Private sitting room" , "Lady's private room" , "Bedroom fit for a lady" , "Milady's chamber" .)
