Would you lose?
Gojo sensei: "Nah, I'd win."
Meaning: A slang commonly used as a theft of food between friends or someone else. Originating from an American Streamer, Fanum, this slang became an internet meme. Soon, Gen Alpha then popularized this slang even further, particularly employing the term.
For example, if someone says "Fanum Tax", that means that they stole your precious food.
Another example: "Officers, those guys FANUM TAXED my french fries. Do me a favor, can you officers FANUM TAX them back?"
Meaning: In Japanese, translated as "You are already dead."
Description: This sentence originated from "Fist of the North Star", a hugely popular fighting genre manga published by Buronson and illustrated by Tetsuo Hara. The story focuses on a post-apocalyptic Earth, with Kenshiro, a warrior who is the successor of one of the most deadly martial arts to mankind, Hokuto Shinken. This type of martial art allows the successor to strike a vital point of a person, which often leads to violent and very gruesome death. But there is a disclaimer about the manga: the manga is NOT to be read by teens under the age of maturity, or like, around age 14 or under, for there is nudity; blood, and guts blowing out. Anyways, speaking of the "Omae wa mou shindeiru" sentence, after the anime adaptation was released in 1984, years later, it became a meme when a song called "Omae wa mou" was released.
It's just "Omae wa mou, SHINDEIRU..." There are no other examples.
