Triangle

Triangle, 3 corners 3 sides , make the pointy little shape with your hands and you've got yourself a pose, easy? yes it is !
this pose has 2 origins:
1. it was the hand symbol that represented Jay-Z's rocafella connection and it means "diamonds are forever" and 
2. it can also be an nba reference that symbolizes "isolation play" and came from the triangle offence of an nba game (a series of passes)

however! it could just be a simple pose for fun - its easy and interesting. 
it covers your face but it could also frame your face in a triangle shape! its pretty, effective and different. so have a go and frame your face into a triangle one day!
