Jidrool means: It’s an old-fashioned Italian-American expression for someone who is mentally retarded. Literally it means a corrupted dialect of the Italian word meaning cucumber. It basically means you possess the intelligence of cucumbers. Because it was used in The Sopranos, the word is now back in fashion in New Jersey. You pronounce it as Jid-DROOL. You must roll the “R”, on Drool. (in Community Dictionary, added by Javier Domínguez)
