1. To deliberately work or perform slowly, sluggishly, or reluctantly; to idle rather than perform one's work or duties. Stop dragging your ass on that assignment, I need it finished by 3 o'clock. I'm so bored with work that I find myself dragging ass every day in the office.

2. To leave or depart from a place. You'd better drag your ass outta here before I get even more upset. It's the cops, we'd better drag ass!
