Pou launched as a mobile virtual pet game in 2012 and became widely known for its simple mini games and cartoon pet care gameplay. Its short game over jingle was later lifted from gameplay clips and shared on soundboards and meme pages, where the two-second sting became shorthand for losing. Creators paired it with gaming fails, school mistakes and sports bloopers because viewers who grew up with mobile games recognised it instantly. It remains popular alongside other classic fail cues like the SpongeBob fail sound, which serves a similar comedic purpose.
