In a new book about the infamous court case, one of the prosecutors described the defense attorney as "smarmy: somebody who is slick, underhanded, and doesn't shoot straight."
Smarmy means "behaving in a way that seems polite, kind, or pleasing but is not genuine or believable." It comes from a word that meant "to gush" or "to flatter."
