A versatile expression, "hose the
cunt" is used in three different ways:
1. As an expression of contempt for a third party not present;
2. As a general rallying
cry;
3. As a euphemism for cunnilingus.
Etymology:
Based on a method used by Victorian-era doctors of masturbating "hysterical" women called the water cure, a.k.a. the pelvic
douche.
To quote Vice magazine:
"Instead of revving up the vibrators, doctors began aiming
fire hoses at
fire crotches. Pelvic douches, which aimed a jet of water at the inner thighs, were installed in mineral baths all over Europe and America in the mid-1800's. Women loved them and flocked to the spa towns where such a cure was provided. R.J. Lane, who wrote about his experiences at a spa in England, said men were somewhat fearful of the pelvic
douche, but women were "frequently known, on coming out of the
douche, to declare that they feel as much elation and buoyancy of spirits, as if they had been drinking champagne."" (Source: "Doctors Created Vibrators After Growing
