Short vocal sounds like Ileee tend to circulate through short-form video and soundboard communities, where a clip that is easy to recognise in under two seconds can travel far without needing any context. Its appeal is in its simplicity: listeners instantly read it as teasing, amused surprise, and creators can reuse it across very different videos without it losing that meaning. Because it is so brief, it also works well as a reaction, a transition sting or a comment on a clip, which helps explain why it keeps appearing in memes and edits after it first started being shared.
