A portmanteau of the words Soju, Maekju, Cola. You will need 2 shot glasses, a regular beer glass, and the ingredients below.

Soju - Korea's famous liquor
Maekju - beer (a glass of it, any brand will do)
Cola - Coca Cola

Pour the Coke into half a shot glass. Stack the 2nd shot glass on top, and fill this one to the brim with soju. Now fill the glass about 3/4 full of beer. Pick up the glass with your dominant hand, and the stack of shot glasses (still stacked) with your other hand. In one swift motion, drop the shots into the glass of beer (hopefully they stay stacked and upright), and immediate start chugging. If you do it right, the 2 shot glasses will separate past a certain tilt angle, releasing the Coke. You'll basically consume a pile of spiked beer, with a sweet cola finish at the very end.

This has got to be the most awesome Korean invention EVER.
