Do without women? (4,5)
I believe the answer is:
stag party
'do without women?' is the definition.
(party or do attended by men only)
This is all the clue.
(Other definitions for stag party that I've seen before include "Men only social night out" , "Wild celebration for male deer?" , "event before wedding" , "Rowdy celebration for men only - or deer?" , "Rollicking night out for men" .)
