Who is Poot? According to the Tumblr user Cstcrpt, who created and delivered her into the world — and has deleted their account since Poot went viral — she is "Demi's twin sister, separated at birth. She was locked in a basement her whole life."Since its inception, Poot mythology has evolved to a much longer tale about how she was shunned by her family for being a weird little kid, which is pretty sad when you think about it. Poot even got her own Wattpad entry , titled "Delete it, fat!"Did we mention someone made Poot an official Twitter account?
