Yet another way of saying "whatever". Very abbreviated, very aloof, very annoying. Mostly otaku use this word, as the Japanese pronouce the English "v" as "b".
The word wutless is not just used in The Bahamas. It's widely used in Barbados and Jamaica (i know of those two for sure)and i'm sure it's a caribbean thing. it means good for nothing, worthless, trouble maker, doesn't care about getting in trouble etc.
