What a hilarious clip, "Superstitions of South East Asia #YTFF". Check it out!
I especially am amused with the skit by LASTDAY Production, about the Indonesian superstition on how when taking a photo (not necessarily just a selfie), it must not take the photo of three persons at one time because the person who is at the middle is supposedly be dead.
Upon further googling, I come to this site, "Superstitions of Indonesia" and this specific entry does not really specify the number 'three', just to avoid 'odd numbers' when taking a photo.
Avoid taking pictures with odd-numbers of people present as this would result in the quick death of one of them.
