In the spirit of Dane Cook, a man sits behind a woman and places his penis betwixt her thighs. He then carefully places a cashew on the tip of his penis, gently pulls his cock down, and lets go- thereby both launching the cashew into the air and slapping the girl's pussy simultaneously. The girl must then catch the cashew in her mouth for the Cashoot to be completed.
It took us many tries until we successfully executed the cashoot.
Past Tense: Cashot.
