A 'helo' style
conversation with someone. Usually this comes down to a short, unexpected message from someone you did not expect to be messaged by. Alternatively, 'helo' can also mean
small talk but with the least amount of effort possible.
The term originates from memes such as "helo fish" where a close-up of an animal looking at the camera, is sometimes combined with the caption "helo", or in another way that depicts someone or something suddenly wanting your
attention.
