Type of party deer? (4)
I believe the answer is:
stag
I believe this is a double definition.
'type of party' is the first definition.
(I've seen this in another clue)
'deer?' is the second definition.
(stag is a kind of deer)
(Other definitions for stag that I've seen before include "Excluding women" , "Horned animal" , "Male at party?" , "party given by Uncle Sam" , "Share speculator" .)
