Global engine fighter in a tunnel full of windy farts

noun

A high-speed, jet-powered contraption resembling a fighter plane, whimsically imagined as a "global engine" (a fantastical, all-encompassing power source) navigating a wind tunnel filled with gusts of flatulent air. This playful term evokes the image of a supercharged vehicle testing its aerodynamics in a comically challenging environment.

After a week of testing, the engineers finally released the global engine fighter in a tunnel full of windy farts, sending it zooming through the air with a trail of giggles behind it.
