Markiplier, real name Mark Fischbach, built a huge following on YouTube with Let's Play videos, especially horror games where his exaggerated reactions became part of his persona. Short clips of his voice were later ripped and shared on soundboards and in edits as standalone reactions, separate from the original videos. This I'm gonna cry moment fits that tradition alongside other fail reactions like the SpongeBob Fail sting. It spread through gaming memes, Discord chats and short form edits because the line is instantly understandable even without context.
