A female that someone dates or marries. That turns into a complete whore. Then tries to gut the individual financially. Comparable to the trench knives used in world war one. Either by marriage or child support for no reason.
Did you hear about Jake the poor guy, got caught up with a trench knife he had to sell his house and boat.

Trench face occurs after at least four days of no sleep and 18 grams of mephedrone or 3 grams of NRG-1. Victims believe that the outside world is the battle of the somme and that their eyeballs have turned into penises.

A very hairy and cheesy vagina, with a deep camel toe, resembling a large trench rat from world war 1
I was about to have a good time with Judy last night but then saw her trench rat and puked in my mouth.
