I speak like a grandma, so my slang lessons will be a Korean AND English lesson for me!
That's why we have Seungkwan seonsaengnim here to teach us Korean slang!
털ㄴ업 - Turn Up!
Friday night? 털ㄴ업! Passing period? 털ㄴ업!! Late night on Vingle!? 털ㄴ업!!!!
핵노잼 - Totally not funny!
We learned this a few days ago here! This phrase does not apply to Seungkwan, because he is full of 잼! He's one of the most entertaining idols out there now!
부비부비 - Booby Booby
Yes, you read that correctly. Booby booby is used to refer to really crowded situations like on a crowded bus or train. You're literally booby to booby with people LOL. I've even heard people refer to 'riding on a crowded train' as 'booby booby time" (부비부비타임)
쉑 - Swag
Do I need to explain this further? It's used exactly how we use it in English (although I cant really even define how we use it in English LOL!)
