Looking for a turtleneck in Korea? You may want to use the Korglish word, "polar" which refers to long sleeved turtle necks.
Instead of saying air conditioning or air conditioner in Konglish people will just say, "aircon".
When someone wants you to finish a drink they will tell you, "one shot!" In The United Stated people would say, "bottoms up".
The names of purses and bags can get confusing. In Konglish a backpack or handbag is often referred to as a sack.
Any longer coat (commonly called trench coats) is referred to as a burberry coat in Kinglish regardless of the brand.
Cunning means cheating, specifically when a student is cheating or copying on a test. A cunning student is a student who cheats.
When you want to encourage someone you tell them, "fighting." This is common before students take a test, a person has an interview, or people otherwise need a little encouragement.
This is my FAVORITE term in Konglish. The Korean culture does not tend to touch as much as the Europeans or American counterparts. Skinship is used to express a type of relationship you have where touching someone's skin is OK.
