Commentary
Reprobate (which includes the prefix re-, "back of backward") is often said in a tone of joshing affection. The related verb reprove or "scold," since the reprobate deserves a constant scolding. Shakespeare's great character Falstaff - a lazy, lying, boastful, sponging drunkard - is the model of an old reprobate.
