It's amazing that no one answered what kind of crying man.
The hero of the meme is a blogger and streamer Ozon671Games. During one stream, he was drunk and felt very much from the clip-cutting of frames of the film "Battle for Sevastopol". However, see for yourself:
The meme really came from Kalda. But they began to force it not because of the absurdity of the second mission. About a year ago, a professional e-sportsman for Kalda (PHiZZURP) died in a car accident. So his funeral was broadcast on Twitch. Most of the fans naturally knew about the existence of the mission with "press F to pay respect" and wrote a capital F in the chat, referring to it. The situation quickly became a topic of discussion and a corresponding meme appeared.
Meme "Press F to pay Respects" came from the computer game "Call of Duty: Advanced Warfare". After the release of the game, players noticed the absurdity (and irrelevant) of the scene from the second mission, in which the player is asked to press the "F" key on the keyboard to "pay respects" ("salute").
The result is a lot of pay respects memes:
The phrase "press F to pay respects" comes from Call of Duty: Advanced Warfare. I went like a meme. Then they remembered Snake from Metal gear solid 3, who also saluted. Well, and somehow merged together
Everything went from Call of Duty: Advanced Warfare. At first, no one paid much attention, and then the absurdity of this scene began to be discussed on YouTube, Reddit, etc.
Anyway, I will salute Billy
