slack ass 

A technican in an analytical laboratory who picks and choose from the queue of work, looking for the easiest jobs to do first and dragging their feet, complaining that this easy work is very complicated and taking a long time to complete.

"Brandon, that slack ass, jumped the queue again and took that easy job last week. Now it is 3 days overdue when it should have been done the first day."
