It's a term for very intelligent yet kind of retarded person. Simos are very academically gifted and excell at every subject except P.E., because of their lack of physical strength. Simos cannot tolerate stupidity, that is why they often tell people to shoot themselves. They get along well among their own gender, but lack experience with the opposite sex. They are usually very arrogant, proud, condescending and sometimes racist, but only towards black people.

Get the Simomug. Simos is the hottest guy ever. He has the best voice ever and amazing music taste. He has the kindest personality and the “skater boy” style. He can also draw really well. If he likes you you are very lucky. But I think he likes a girl named Stefania.
