The region of the body where the distinction between the thighs and the butt have been eliminated. Typically found in overweight and obese individuals, though the condition may also be an unfortunate symptom of pregnancy (due to swelling of joints and tissue). Closely related to the term "cankle," it is a portmanteau of the words "thigh" and "butt."
I used to have such a well defined booty, but after my first child I'm now stuck with this awful thutt. At least my cankles have gone away.
