Airman Underground

A discreet communication channel used among those in the Naval aviation pay grades E-1 thru E-3 to keep Naval aviation pay grades E-7 and above out of the loop. It often adds fuel to the fire and the cause of rumors.

I don't know who she's fucking, but I bet the airman underground knows tho.

underground jungle

another way to describe a subway, metro, or tube in urban areas such as New York, Boston, or London.

I feel like I live in this underground jungle. Maybe I should start riding my bike to work.
