The axe wound found on women or an adventure play ground found right next to a sewerage outlet. It can be bald, hairy, a landing strip, trimmed and manicured. It can be smelly - like fish - taste tangy or if you are lucky, be completely neutral and delicious - you'll growl for hours if this is the case. Can also be an ini or an outi - look like a badly packed kebab or a nice sweet freshly cut mango!
Bob was at the local pub and saw a nice looking gal, he said to his mate Phil "I wouldn't mind going the growl on that vagina." meaning touging her out.
