The your mom is gay line comes from old playground and schoolyard insult humor that later became a staple of internet prank culture. Rather than tracing to one video or creator, it spread through soundboards, Discord servers and meme pages as a reusable roast. Short voice clips like this one are popular because they are instantly recognizable and need no setup. Creators still use it for reaction memes, gaming highlights and fake argument edits, where a quick low-effort jab keeps the tone playful instead of mean.
