Thut was discovered by Brian Williams is 2015 of April. It means when a girl is or boy is a Thot + A Slut. If someone calls you a Thot. Call them a Thut.
When a woman is sooo thick that her knees, shins and ankles are invisible so it looks like her entire leg is all thigh and then foot, becoming a Thut! Similar to a Cankle, which is a woman’s extremely thick Calf-Ankle!
