The ringtone comes from WhatsApp's desktop and web applications, where it plays for incoming voice and video calls instead of the phone's default ringer. It appeared when WhatsApp brought calling to its desktop app, and uploaders later ripped it for soundboards, prank compilations, and meme edits. The tone spread because the melody is instantly tied to the feeling of being called, and louder variants such as a bass-boosted WhatsApp call tone are popular for comedy intros. It remains a staple notification-style sound online.
