A type of whip formerly used as a torture device, mostly for lashes in punishment of crimes. It is now used by BDSM partners, though usually without the death and severe wounds.
My ass still hurts from that cat o' nine tails she used on me.

A whip, usually leather, with nine tails. A variation on the Egyptian flail. Hurts a lot. Often used in bondage.
Sometimes, my lover ties me to the bed and uses the cat o' nine tails on me.
