This short article focuses of the language nationalism as a very common form of applying a nationalist behavior. The language nationalism is presented throughout empirical examples of some Southeast European countries and their method of exercising or dealing with it. The article begins with a metaphor of a party place for students from one university in Bulgaria, where in order to sing all songs, students need a familiarity with the language of their neighboring country. The article is trying to prove that the process of intensifying the process of studying foreign languages will provoke cultural and professional exchange among the nations and hence, will control the nationalist tension.
