noun

A person who slumps or slouchs; a sloucher, drooper.“Then, as soon as you walk away from the mirror, you slump into the old comfortable position, with the result that your hemline sags forlornly down in the back. If you’re a slumper, might as well face facts and stand that way when your clothes are being fitted, then allowances can be made for droop-osis. But do something about it, won’t you?”
