I've been watching Lethal Weapon and stumbled upon the word
gaflooey. Here's some context:
Roger: "What you got?"
Riggs: "Part of the device. This is artwork. This is goddamn artwork."
Roger: "Well, I'm glad you like it."
Riggs: "You don't get it. This is real pro stuff. I haven't seen anything like this since the war. The CIA used it to hire mercs. They used the exact same setup. Mercury switches,
gaflooey. That's heavy shit!"
What does the word
gaflooey mean here?
