blue falcon

euphemism In the military, a "buddy fucker," someone who betrays or otherwise causes problems for their friends or comrades. Can you believe Stuart ratted us out to make himself look good to the corporal? What a blue falcon. You can't trust a blue falcon like Mitch—he's only motivated by his own self-interests. I told him those guys were blue falcons, but he wouldn't listen. Hopefully, he's learned his lesson now.
