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.
Wutless is a word derived from the English word “worthless” used in the Caribbean community to describe someone who is good for nothing, useless or a waste of space.
