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.

If you go to bed too late, the next morning you wake up with a tired line under each eye. After many late nights they resemble trenches! :(

a person that is EXTREMELY..... ugly. like beyond the point were you cannt look at them for one second or else you will puke. a trench face must walk in public wearing a thick black unsee-through bag over their face at all times. they can not take it off for any reason what so ever.

its would be like having trench foot, a disease during world war 2 caused by a person having their foot in muddy water for months and the cells in the foot die. and has black spots all over with blood leaking out. also the skin around the infected area is rotton, or is pealing off. due to the dead cells in the foot.
