A comment from a reader:
I have a few words I see a lot on the apps. It took me a while to figure out what they mean, so I think it'd be cool if you addressed them here: 시드(해요), 에셈, 연애, 물건. Thanks for this great blog!
So, let's talk about these words!
시드 is a video calling application. I'm assuming guys video chat and do dirty things.
에셈 is S&M. It kind of has the same sound if you say it quickly.
연애 is a relationship. You could say something like 연애하고 싶어요 (I'm looking for a relationship).
물건 is another word for penis. It literally means thing. 걔 물건 크던데 (His thing is big)
