Term adopted by fans of CBS-TV's police-procedural drama, THE MENTALIST. Came from a typically offhanded slighting remark by title character Patrick Jane (Simon Baker). Refers to the kind of just-barely-dressy beachcomber-type sandals often worn by Teresa Lisbon, co-star (Robin Tunney).
"My firm is very conservative and frowns slightly on Lisbon Loafers, even in the summer. Actually, policy is kind of hypocritical because no one minds secretaries in them, but nonetheless it's a big turn-off to HR when a women interviews in them. Unfair, no?"
