When something is good it is often know as pro gravy, derived from the native tongue of the Blackest Man In Dunmow Dicky "pro gravy" Davies. Can also be split to start and end a sentence to emphasise the pro gravyness of the said sentence!
...That is one Pro Gravy bike maaaannnn"
...Pro do you fancy going for a ruby and a beer at a curry house gravey?
...Pro my bird is a tequila girl and used to lap dance gravy!!
