A military term for something truly shite.
Often used to describe the very presence of a lower rank.
1) - "Oi Private, your kit is proper gash. Fucking sort yourself out, and get the fuck out of my face." - some Corporal.

2) - "Every single one of you is in gash state. Fuck off." - Probably the same Corporal.
