1. adjective, slang Crazy, eccentric, foolish, or senseless. A glib adaptation of the word "lunatic." Also spelled "looney" or "loonie."

slang A psychiatric hospital or insane asylum. From a glib adaptation of the word "lunatic," the phrase is now considered tactless at best, extremely insulting at worst.

When she joked about putting someone like my brother in the loony bin, I threw my drink in her face and walked out of the restaurant.

Insane asylum. The word “lunatic” comes from the word for “moon”; madness was associated in many cultures with the effect of the phases of the moon on the human mind. From lunatic came loony, and loony bin was where insane people were incarcerated. The phrase is now considered insulting in the extreme, as are “booby hatch” (originally a covered passageway down a ship deck), “funny farm,” “drool academy,” and “foam rubber city” (a reference to padded cells).
