why is urban diconotiry more an authority on grinding the corn than wikipeida

Term for a sexual technique. Picture the action of grinding corn with a mortar and pestle, but grinding along the rim instead of grinding in the bowl. A penis is the mortar and a vagina is the pestle, with her pubic bone (and clitoris) the rim. Heard in an episode of HBO's "Six Feet Under", Original Air Date, 15 August 2004 (Season 4, Episode 9).

Also known as Coital Alignment Technique, a variation on the missionary position in which the man shifts upward just a bit, so his pubic bone stimulates her clitoris while his penis is still entering her vagina. This position provides maximum contact with both the clitoris and the G-spot (of vaginal intercourse).
