Yoo! 

A form of greeting in West Cornwall, England. Used instead of any other common form of greeting (Hi, Hey, Wotcha, All right?) in places such as Causewayhead - the pedestriansed 'Main Street' of Penzance, the place where famous eco-protester Swampy used to busk between anti-road building gigs.

It is not clear if the word means 'you' (as in 'hello you') or even perhaps may derive from the Ancient Cornish word for Thursday (as in 'See ya Thursday')

Whatever the derivation (and this is not made up - honest), this is the ultimate example of modern Cornish - a term routinely used by surfy types, photopgraphers and djs who have all but replaced farmers and fishermen, me handsomes (now that's old Cornish)

PS Penzance is very 'urban'. Not a village no. Yoo!
