1) A move exhibited in wrestling, in which you grab ahold of the opponent, arcs your back and thereby slams the opponent into the ground, head first.
2) A sexual position most commonly used within a presbyterian sect in eastern
Germany. The members believe the the arced back of the
female participant keeps her pure, while also allowing for easy penetration for the involved male. The flow of blood to the
head can have effects similar to autoerotic asphyxiation, thus causing pleasure for the female involved.
