An advanced sexual technique in which a woman consumes a large amount of French onion soup prior to lovemaking, then proceeds to release a yellowish discharge while her partner is performing cunnilingus. The flavor closely resembles that of a decomposed onion.
Guy 1: "Last night, Jane gave me a decomposed onion."

Guy 2: "Shit, that's disgusting."

Guy 1: Actually, it wasn't as bad as I expected. I'm heading by her office in about an hour to do it again!"
