Christmas party? (4)
I believe the answer is:
magi
'christmas party?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for magi that I've seen before include "The three Wise Men of the gospels" , "Eastern men of lore; Epiphany figures" , "members of priestly caste" , "Biblical wise men" , "Christmas travellers" .)
