A portmanteau of the
words, "urine" and, "silencing".
The act of, when passing micturition (urine), pissing onto the inside of the toilet
bowl above the waterline or against the back wall of a wall urinal so that the, "urine splashing into
water" sounds are totally absent.
{Husoos}: Hey Horhay, where's Edgar? He went into that restroom a few minutes ago, but I
don't hear any
pissing sounds.
{Horhay}: Edgar is urincing -- that way
nobody will hear him peeing.
