A term used by Barney and Robin on "How I Met Your Mother". While having kinky role-playing sex this is their safe word when one of them goes too far. It can also be used in other situations when someone has gone "too far" as in the telling of dirty jokes and stupid comments.
If someone is a little too kinky during sex play or if someone goes a bit too far in the telling of a stupid story or idiotic banter on any given subject. "I call FLUGLEHORN!!'
