that originates from the village of Brockenhurst, Hampshire, United Kingdom. It stands for Boys of The Wood, as Brockenhurst is in the New Forest. One tag has been found in Sway, a nearby village. It was found on a fence down a rather mouldey smelling alley-way, on the way to the village from Nick's house.
Nick: Hey Josh, you gonna do some tagging tonight?
Josh: Yeah B.T.W. is gonna be sprayed on every fence within a mile of Brock!
Nick: Yeah well I'm Sway for life so I can't join you tonight, maybe you should move to Sway.
