Get the Retardi b mug.
a retardi b is someone who thinks they are cooler than everyone else just because they know all the words to Cardi B's songs. they think they are cool but in reality they look very stupid, hence the name, "retardi b"
"ugh there maddie goes with her stupid rapping"
"i know, she thinks she's talented but shes really just making a retardi b of herself"
