The CORRECT 3 meanings (a common misconception is a female is a gash in england, never have i heard a woman called a gash and i wouldn't advise trying it either)

1. A female vagina

2. A cut

3. Something bad

1. That bird has a lovely looking gash, she showed us in the pub. it did smell tho which put us off

2. I got a massive gash on my arm

3. Work was gash today

Vagina; female genitalia

Origin - possibly due to appearance but more likely a reference to menstruation as the word properly means a wound (bleeding). Not a nice word to hear in a sexual context but evocative of monthly messes - e.g
In the past few days my "cunt" has officially changed identity and become my "gash"
