trench pussy

Like trench foot, when you've been sitting around in a pad for a while and it starts to get mushy so that pussy needs amputation

TrenchPuss 

Female genitalia that has been moist/sweaty/unclean for a long period of time, promoting unfavorable aromas.

In reference to the WWI term "trenchfoot" where soldiers who did not change their damp footwear developed rotting flesh on their feet.

She had a bad case of trenchpuss...

Trenchpuss 

A vagina that has been used so hard that it resembles a trench that an entire battalion has called home...and will never close to its original shape again.

The trenchpuss was so overused that it could no longer return to a vertical smile and is now stuck in a permanent o-face.
