If someone has a bad reputation, why do we say they have a “bad rap” and not a “bad rep”? After all, “bad rep” is just a shorter way of saying “bad reputation.”
True as that may be, the phrase is in fact bad rap.
Confused? We’re here to help.
The word “rap” originated as a way to describe a punishment (think “rap on the knuckles”) and evolved to be slang for taking the blame for something. From there, it came to mean a prison sentence or criminal indictment.
The term “rap sheet,” meaning police arrest record, was first used in 1949, according to Merriam-Webster, and after that “bad rap” made its way into the written word more and more often starting in the 1960s.
Tbh, we find it a little awkward that the very definition of this usage of “rap” contains the word “reputation,” but we don’t make the rules. We just research them and give you advice. In this case, we advise you to use “bad rap” to avoid getting a, um, bad rap.
