Roasting someone means that you know how to be tactfully mean (snarky) without being mean-spirited in poking fun at someone, teasing, ruthlessly ridiculing, trash talking, and even mocking them.
Roasting people that you know is usually a bad idea because people will believe that there is truth in every joke and might laugh in the moment but remember nothing but bitterness, which is why roasting should be reserved for when a person truly deserves it.
