Little is known about the original recording behind aalooo, so its history is mainly the way it has circulated as a short shareable clip. The elongated spelling matches the way the voice drags the word out, which makes it easy to search, title and reuse across soundboards and edit packs. It has found a place in casual meme editing where a loud, friendly call can stand in for hello, wait or what is happening. Its short length and clear single voice keep it reusable in many different contexts.
