An endearing name for "Chad" as taken from the animated series "American Dad." Used by the alcoholic, under-cover, efeminite alien, Roger, who lives with CIA agent Stan Smith and family in their attic. He uses the nickname while on the phone with some "Chad" person. He combined Chad with Daniel to get Chadiel, to change up the name...in Roger's unique, sarcastic method of dealing with people.
Roger on the phone: "OK, Listen Chadiel, it was really nice talking to you, but I gotta go now" *Click*
