A popular drink with Korean youth. Basically a glass of beer (maekju in Korean) with a shot of Soju (Korea's most famous product besides RAM chips) added for good luck, hence the name.
The best part of this drink is that it doesn't taste any different from regular beer, but messes you up 3 times faster.
A variation of somaek is poktanju, which is a shot glass of soju dropped into the glass of beer and chugged, similar to a Jagerbomb.
That hot Korean chick opened her legs after a few glasses of somaek.
Nicholas Cage used the ace up his sleeve known as "somaek" to get with his current wife.
