An English slang word for; "vagina is vagina" or "pussy is pussy". So basically a person, who uses the term "gash is gash" is just pure twat and a fuckboys, who has no respect for women and just uses vulnerable women for sex.
So if your top lad Gary (also known as Gazza for his top notch banta) has just slept with his psycho bitch of an ex-girlfriend, Britney, and you ask;"Oh Gazza you fucking bellend! The fuck you doing with Britney?!" And Gazza the fucking legend replies with "Well lads, gash is gash! now lets go get us a cheeky Nandos en boys!" You just sit there thinking, well cant argue with that. You then strut down to Nandos, with all your swag, and get on the banta bus with a one way ticket to top notch bater vill.
