modern kids will never understand unless they're ancient weaopn enthusiasts/experts (explanation at very bottom, optional spoiler if you just wanna find out what this meme means)
The sickle in N1 is used as a weapon, but it's users are terrible and it is an adopted symbol in the game of "combat indecency", simply unacceptable, dishonorable ways. The Shotel is another bladed weapon originating from what is now modern Eritrea and northern Ethiopia (in Africa, near the Middle East.), these blades were likely made by the D'mt and Ammon peoples (cool guys who don't spam). The Khopesh is another sickle shaped bladed weapon likely originating from the bronze age Canaanites, Kush, or Nubians (some more cool guys who don't spam) in Ancient Egypt :D
