H.S.K.T
A wild party where you have to let five people do whatever they want to your head, shoulders, knees, and toes, and you're not allowed to cry.
My sister did H. S. K. T. and now she can't walk.
My dad said H. S. K. T. is the worst thing he ever did.
My neighbor's cat joined H. S. K. T. and now it can't climb.
