I think LB is referencing LV, Hong Kong verbal shorthand for Louis Vuitton. *** Sidebar *** The amount of dedication that HK (Asia in general) people put into brands and labels is stultifying. I myself couldn't care less, but I guess it does drive a part of the economy.
I JUST LOVE!!!! those names. I watch too much OP. me and a mate are always pointing at the LV shop and yelling LB aR!!
