look up any word, like donkey punch:
A california smore is when one, usually a retard, decides to eat a marshmellow out of another person's butthole. Often results in public humiliation.
Did you hear that Brian M. gave some girl a california smore? What?!? no way! Did he atleast get some afterwards? Nope. Some fat girl broke it up.
