Shared in the WhatsApp audios category, this clip has no clear credited source, performer or original recording attached to it, so its life is mainly online as a forwarded voice note. The Spanish phrases alooo and soy yo make it easy to understand even out of context, which helps it travel between Spanish and Portuguese speaking chats. Its extra long running time sets it apart from short reaction sounds, and people keep reusing it for prank calls, drawn out greetings and moments where someone announces themselves in the most obvious way possible.
