i know, you know, lee know

basically a goated phrase in the STAY fandom for the StrayKids member lee know which is a play on his stage name.

it's also said in the song JJAM.

Person 1: Did you know that you should stream Chk Chk Boom by StrayKids?
Person 2: I know. In fact, I know, you know, Lee Know. Anyways stan SKZ for clear skin.
