Binod is a meme which was originated by a guy named "Binod Tharu" commented binod in his comment (he commented his own name). So a youtuber team named "SlayyPoint" reacted to this and all of a sudden everyone started commenting binod on their video. It kept spreading and it was just a matter of time people started to spam this in nasa's live stream. I hav seen discord servers with Binod-Spam channels. This thing is so annoying especially when you are a youtuber. Binod is meant to be a spam.
