The phrase " Be Clever " comes from the turkish phrase " Akilli ol " which literally does mean be clever. Although be clever does not make grammatical sense in the english language, it is shouted regularly by angry turks when they are trying to tell someone to shut the fuck up or just stop being a bitch.

Big TurkCem: "EVERYONE FUCK OFF, BE CLEVER!!!!"
