A game of Yugoslavian Roulette is very reminiscent of "Russian Roulette" except it is tradition to use a fully loaded revolver, a semi-automatic pistol, or whatever gun you can think of that holds its ammo in a magazine.
On April 30th of 1945, the Führer of Germany brought it upon himself to dabble in a small game of Yugoslavian Roulette in his underground bunker; signalling his defeat.
