A neurophysiological disorder that occurs in certain people (usually a girl, usually named Kalina) who are irrationally happy all the time. As a result, they are never able to stop their eyes from smiling, even with strenuous effort. It is a very unfortunate condition that causes immense career success and likability. Condition is currently incurable and is spread by direct interaction with others. Please beware.
