underground jungle

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

Underground Mafias Army

A Club Penguin army community full of absolute wetwipes. Typically they go on Club Penguin Rewritten and try to annoy innocent players going about their day. The HCOM is clueless as well.

Did you hear about the Underground Mafias Army again? They're a bunch of nimrods.

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.
