Marios is the guy always reading non educational books but studies only when he is taking exams. He wears glasses and cannot decide how to make his hair so he gets a yee-yee-ass haircut. He is calm but when he is in a good mood he spams with jokes and laughs screaming. He is the right guy to tell the sins that you have done but he will make jokes about it. He is an atheist and also he is suicidal.
If someone tells you a very bad secret and you ask them to commit suicide with you immediately you are a Marios.
