omae wa mou shindeiru 

Something from the anime/manga series ‘Fist of the North Star’, meaning ‘you are already dead.’ And then the person it has been said to dies. If you hear this said, it is completely unacceptable to not say ‘Nani?!?!?’.

Random person: omae wa mou shindeiru
Me: *appears behind them* NANI?!?!?!?!

Mou Ikkai

Mou ikkai is the romaji for もう いっかい meaning 'one more time'. Popularized by Wowaka in his song 'Rolling Girl' and has come to be a staple in his music. In Rolling Girl it is written like this: もう一回. Though Wowaka has sadly passed on, his music has inspired many other vocaloid artists to start in the first place. Mou ikkai is now in many songs and even included in one of my personal favourites, Amanojaku.

Hatsune Miku: Mou ikkai, mou ikkai, watashi wa kyou mo korogarimasu to.

st'arxidia mou 

'Sta arxidia mou' or 'st'arxidia mou' (pronounced, star-he-dee-a-moo) is a popular modern Greek saying that directly translates: "to my testicles" but refers to writing something you don't care about on your testicles. It roughly means I don't care, or I don't give a shit.

Someone: Hey I just saved a bunch of money on my car insurance!
You: St'arxidia mou!

Someone: If you do that you will get into trouble!
You: St'arxidia mou! Did I ask you?

Omae wa mou shindeiru 

'You are already dead' in Japanese. Legend says that if you say "Omae wa mou shindeiru." to an opponent, their response will always be "NANI?" meaning 'WHAT' in Japanese. Then said opponent will die. If 'Nani' is not said, then...? The opponent will die anyway though.

"Omae wa mou shindeiru."
"Nani?!"

watashi wa mou shindeiru 

"I am already dead"
Deriving from Omae wa mou shindeiru, it is usually used unironically among friends. It is also a cry for help that will be laughed at as you circle into the depths of despair, leaving behind any sanity you possess.

Joseph: Are you ready for the two hour school assembly?

You: "Watashi wa mou shindeiru!!!"
