The Eros sound comes from a user-generated soundboard, where short named clips are uploaded, shared, and replayed by visitors. Its exact original recording is not documented, so it circulates the way most board clips do: people find it, press play, and pass it along in edits and chats. The name gives it an instant identity, which is why it keeps getting picked up as a quick tag or sting. Short, name-based clips like this one tend to stick around because they are easy to recognize and effortless to reuse.
