Family reunion attendees
I believe the answer is:
aunts
'family reunion attendees' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for aunts that I've seen before include "Relatives get a peculiar US tan" , "Elderly female relations" , "Relatives get bad US tan" , "relatively speaking" , "Relatives get an odd US tan" .)
