the more you know 

A reference to NBC public service announcements which would feature celebrities reciting a random (usually touching) fact, followed by the statement, "The More You Know."

Thus, a person may say this after reciting something that is not necessarily useful to the listener. It may also indicate that the user does not expect a response from the listener.

Often rendered like a tag, e.g. #themoreyouknow.

Phil: Sup dude?
Bryan: chilling.
Bryan: brb, gotta poop
Bryan: The more you know.
Phil: ...

I know what that's about!

something to say to somebody when either you are not listening, don't give care about what they are saying, or when you actually have NO EFFING IDEA what they are talking about. A very good closer to a conversation you are trying to walk away from.
You need to be careful, because used too often in the wrong situation, the insincerity shows through.

"So, I was at that office for over two hours and then they had me go down town and talk to someone who it must have been her first day. And long story short, I still don't have my reflectors back from the warehouse."

I know what THAT means 

A verbal prank commonly used by in a conversation, with the intent of annoying the listener. In this prank, there are two parties having a conversation: person A (the pranked) and person B (the pranker). Person A makes a simple, innocent remark with no double meanings. Person B initiates the prank and replies, "I know what THAT means" (note the emphasis on the word "that").

The prank is that person A begins to feel insecure or uncomfortable about what they have said, because the phrase, "I know what THAT means" gives the impression that person B misunderstood what was said (i.e. thinks it has a sexual meaning, or thinks they're lying about something). Person A is completely unaware that person B is just trying to annoy them.

After this, person B could proceed to only say, "I know what THAT means."

Dwight (person A): Hey man, I just remembered, that new Eminem album is out today! Wanna go get it?
Jim (person B): I know what THAT means...
Dwight: Um, what do you...think it means?
Jim: I know what THAT means...
Dwight: **quizzical look on face** um, all I asked was, wanna get the new Eminem album...?
Jim: I know what THAT means...
Dwight: **getting kind of annoyed** do you wanna get the new Eminem album or not?
Jim: I know what THAT means...
Dwight: **more annoyed** what does it mean?! Eminem album or not?
Jim: I know what THAT me--
Dwight: **angry** WHAT? WHAT?!
Jim: I know wh--
Dwight: WHAT DOES IT MEAN??!! WHAT??!!

You know why I’m here. 

Often accompanied by someone playing a few seconds of the song titled "Sicko Mode" by Travis Scott, they are the cursed words every single McDonald’s employee had to listen to day in and day out every single day between September 8th and October 4th 2020 when excited customers came to order the meal at their local McDonald’s, some even visiting several as they reportedly had shortages on common items found in the meal due to the popularity of the promotion. If you’d like to see some of this madness for yourself, search up "you know why I’m here" on YouTube. (Without the quotation marks.)

McDonald’s employee: Hi, welcome to McDonald’s can I take your order?

Customer: You know why I’m here. (plays Sicko Mode)

Employee: *sighs internally* You want some Sprite with that?

Customer: Yeah.

d'you know what i mean? 

Used at the end of a sentence as a rhetorical question. Habitual question used excessively rather than an actual question that requires an answer, with no reply anticipated.

"It's bloody freezing out here mate, d'you know what i mean?"
