A adjective that can't be used to describe anything at all excluding some religiousexceptions. Some people still use it anyway even though their sentence is wrong.
Person 1: Your drawing is so perfect!
Person 2: Thanks! But it isn't that good, nothing is actually perfect, and everything can improve!
Person 1: That explanation was perfect, I understood it all!
Person 2: bruh
There is no such thing as perfect. Everyone has done at least one thing wrong. And everyone is different, so there’s no way everyone has the same option on what perfect means. Well we may not be perfect, we can do our best to be good.
