The 'Vossi Bop' is a viral dance created by Twitter user @NL_Vossi back in 2015. The dance involves leaning forward and bopping to the beat of the song you're listening to.
When you are on a virtual platform, let say a meeting or a conference, and someone enters your space to chat with you, or to see your booth, and you reach out to them, and they ghost you virtually= Vosting.
When you go to conferences now, they used to be live events, however, they are almost all virtual events. People enter virtually into your virtual exhibit hall, and your virtual booth to chat or talk with you. A lot of times, they enter, and you are forced to say "hi, how are you, what can I do for you today, let me tell you about our service or product", and then they just sit there, virtually, and eventually they disappear. Virtually ghosting you. Vosting.
