vajungle
An impenetrable, probably sloopy, vagina in a state of extreme overgrowth.  Accompanied by oppressive and possibly deadly humidity level and dankness.  Likened to the triple canopy jungles of southeast asia.
Dude 1:  Man, what's that gnarly stench?
Dude 2:  Oh, I just hacked my way out of a pretty rough vajungle.  Take my beer goggles away, bro.
