What is BNB slang for Tiktok?

I've been seeing the acronym 'BNB' being used quite frequently on TikTok, and I'm not quite sure what it stands for. Could you possibly enlighten me on this? I'm really curious to know if it's some sort of insider jargon or a reference to a popular trend or challenge. Given your expertise in the realm of cryptocurrency and finance, I was wondering if it might have some connection to that world as well. Either way, I'm eager to understand the meaning behind this abbreviation and how it's being used within the TikTok community.
