The tossing of an individual onto his/her bed, typically children, for a fun bedtime ritual. This word originated in the Bay Area of California circa 1945 - 1950 when a father invented a bedtime ritual to make the experience something to look forward to. You swing the child at least to a three count (count to their age if you can handle it) and then toss with the excited announcement, "Valincha!"
Every night at bedtime, Daddy gives Sally a valincha.
