Know it all 

A know it all is someone who thinks they know everything, and refuses to take anyone else's opinion into consideration because, naturally, they know it all. Also known as a Brian.

I have green eyes but my boyfriend Brian insists that I have hazel eyes. Clearly he is a know it all.

Know-it-all

A name given to a person that expresses basic common knowledge about a subject, by a person that doesn't know shit about fuck on said subject.

Me: Hey Edgar, maybe you should just check to see if the outlet is blown before you start taking apart the DJ's mixing board.
Edgar: Oh dang man, that actually worked! Quit being such a know-it-all, you're making me look bad.

We all know 

Yeah, Amy. You do. You all know that I could frost donuts harder. BUT... Why would I want to? I don't want YOU to have to frost donuts. But you CLEARLY want me to have to sit here and frost donuts. Why? Because it makes your life easier. Not mine. I live in abject poverty, I was lied to about the availability of full time employment and turned down another offer to get it, and I have been (and this is ALSO something you all know) harassed here at the place. You also know where this is being sent and RATHER THAN... Telling me that... YOU are trying to keep me here. This is just incarceration except without a trial. Even Noah got a trail before they locked him up in a group home.

Hym "We all know that it is a waste of my time for me to even be here in the first place, Amy. Why even waste your own time trying to appeal to me? I'm at 0 right now. I'm either going to go down to -1 and it will be because I start stabbing indiscriminately until I am killed. OR I'm going to go up to 1 and THAT is only going to happen if I get the credit I deserve and am compensated for my extracurricular contribution to society. I don't really care either way. I mean I do love to stab... But I also like to be exalted as a hero... But I'm pretty ambivalent about it."

We all know you read the thesaurus

A phrase used to describe someone who uses fancy and/or excessive speech. In the context of Limbus Company, the phrase was used in a scene where a character explains as if they read the thesaurus, causing one of the main characters to call them out.

Person A: I was struck with sorrow upon the sight of their entrails. In fact, I had gained an epiphany: why must the innocent bear death and mutilation for a root impertinent to them? Had the madmen been any wiser, the townsfolk would have not suffered this tragedy, and would live on to an untroubled life.

Person B: Yeah, we all know you read the thesaurus. So anyways, you saw those poor innocents’ corpses and you want us to take revenge? Y’know we’re not some heroes fighting for justice.

mister know it all 

Mister Know It All is the annoying person that has to tell you that he knows the best. Mister know it all feel the urge to correct everyone if he believe he is right (wich is very often).

Tim: oh, look at that white cat, it's so cute!
Jim: what white cat? I can't see any white cats here. Oh, you mean the white cat with some grey dots on it's forehead? Cause that isn't a white cat. That is a semi colored cat....

Tim: can We just warm up some noodles night? I feel like eating something easy, the japanese way.
Jim: uhm, noodles are actually chinese and not japanese, just so you know....

Jim is the annoying Mister Know It All in this friendship.
