Schving or Schving Schving refers to
sphincter, to be precise: the outer anal
sphincter which is under voluntary control.
Coined by Max Keiser as a way to express, in television broadcast, the dangers of inviting violation of the sphincter by way of insertion of sharp or pointy objects, usually repeatedly, by aggrieved parties subjected to involuntary control over their lives and finances.
A sphincter is an anatomical structure, or a circular muscle, that normally maintains constriction of a natural body passage or orifice and which relaxes as required by
normal physiological functioning.
