Lee Know

He's Stray Kids' Main Dancer. Fans and members call him as the Dancing Gem, because that's what he is. He chose this stage name because he said he knows himself and wants to know his fans more (that's the most precious thing ever). He's a dad of 3 wonderful cats (Soonie, Doongie, Dori don't forget their names). He's also known as a fun and caring brother to his members.

Friend 1: Have you seen Lee Know's Dawn?
Friend 2: Of course! I heard he helped composed the song and choreographed the dance.
Friend 1: Lee Know is really great.

I like him but I don’t know how to tell him

Now if you like a boy and you might be a girl or a boy and you are unsure how they feel a lot of people understand. Now the best way to deal with this is to get to know him better, get to know about his sexuality and how he deals with situations like in relationships. If he deals with them well and he flirts with you, you're in! But if he shows no interest in you or asks you for pics, drop him! He ain’t worth it!

Keliah: I like him but I don’t know how to tell him.

I know you are, but what am I?

It's quite simply the most retarded comeback someone makes when they've completely lost the argument. This statement signifies that the argument has gone to a completely immature level. Below is a hardcore argument starting with the immature statement :)

Person 1: I know you are, but what am I?

Person 2: Good question. What are you?

Person 1: Wow, you're so dumb, you don't even know what I am?

Person 2: You're so dumb, you can't even answer my question.

Person 1: I don't answer stupid questions. Sorry.

Person 2: Then you shouldn't have made your first one.

You-Know-Who

A person, usually an acquaintance, who you find completely detestable. The mere mention of their name is enough to fill you with a feeling of dread, while an encounter with this person inevitably leaves a cloud of misery hanging over an otherwise pleasant day. This term is derived from a common reference to Lord Voldemort from J.K. Rowling's Harry Potter series.

"I bumped into You-Know-Who the other day...that basically ruined my week."

how the hell should I know?

An aggitated responce for when someone asks you a question you cannot possibly know the answer to. Usually said in a tone that is more or less telling the person to fuck off.

Guy #1: Where did I put my pen?
Guy #2: How the hell should I know?
