A Soju Bomb is a cocktail which mixes beer with soju, a Korean grain-based liquor with a very high alcohol content. Simply stirring the liquor into the beer is totally inadequate. The real Soju Bomb experiece begins with balancing the shot of soju over the beer glass on a pair of chopsticks. Knock hard on the table on which it sits to jar the shot loose. To fully prepare your brain for this experience, use something heavy, like your skull. Get your head nicely tenderized so that the booze has pain to numb.
If your shot does not fall in, try again and again, as many times as necessary, to mix the drink. The more times that you hit, the more motivation you gain to complete the drink.
