 Đujić's mother wished to name him Simo, after his uncle.Đujić's father disliked the name and, having been raised listening to the "gusle" and reciting Serbian epic poetry, named his son after Momchil, a 14th-century brigand in the service of Serbian Emperor Dušan the Mighty.It was not until Momčilo started primary school in 1914 that his mother discovered that he had not been named Simo at his baptism.
