For most people, the term "Boop" has no association with the meaning of getting somebody's attention. Consider alternatives! "Nudge" was a term used during the Windows Live Messenger era to highlight user chats without directly asking the user to respond. Other alternatives which could be considered are "Poke" and "Prod," although nudging somebody makes a lot more sense thematically in VRChat as a whole, since it can be considered an evolution over the old era of real time discussions.

The name is cute, but has little to no meaning for the general population beyond furries and anime enthusiasts.
