Slipshod is an adjective that means sloppy or careless.

Our word of the day entered English in the late 16th century as a word for ‘wearing slippers or loose shoes,’ an appearance that some people thought of as lazy or sloppy. In time, the word become a synonym of ‘sloppy,’ as in: Don’t get me wrong, Chuck has a lot of talent as a mechanic, but his work can get a little slipshod — especially when he doesn’t have the incentive to pay attention to details.
