inseong 

Someone with sweet voice that could melt any hearts just by talking. Really cute smile. Tend to be insecure but actually have the face that people would be jealous of.

Wow, look at her. She is so inseong.

inSekur

Pronounced in-Se-ker, it is 1 of 3 words Kanye West believes are a part of the US dictionary. Assuming this word is supposed to be insecure, Kanye West's long time speech impairment or shortage of time in the studio to notice that these three words were pronounced with a speech impairment were placed into one of his ridiculously smooth flowing, awesome,unique, talented, rhythmic, original, sensual, genuine, bombtastic, tasty rhymes. To be rhymed with Cawur (Kanye West's version of Career?) and Sekur.

Kanye West - "All Falls Down" 23 seconds in

"Tell me that aint inSekur, the concept of school being so sekur, sophomore three years aint picked a cawur"

Yes this album won awards for rhymes like this.......

Inseong 

Inseong is the love of my life. I love Inseong so much, I hope he wont get sick during this pandemic. Inseong is the BADDEST BITCH and the nicest angel at the same time. Inseong could also be known as Lee Jaeyoon’s girlfriend.

Inseong’s voice is so good. Inseong is so sexy. Inseong is so cute.
