Vsco Girls:

And I Oop

Oop = 3 letters

3x2 (average scrunchie amount) = 6

6x111 (average brain cell amount) = 666

666 spoken really fast sounds like sksksk

Messy buns hide the devil horns

Oversized t-shirts hide the bat wings

Hydroflasks contain blood and bones of enemies

Theory: vsco girls are spawns of Satan himself
