Is Bonk under Solana?

Excuse me, I've been following the cryptocurrency scene for quite some time, but I'm still a bit hazy on some of the details. Could you please clarify something for me? I've heard the term 'Bonk' mentioned in the context of Solana, but I'm not sure how they're related. Is Bonk somehow under Solana? Or is it a separate entity with some sort of association? I'd really appreciate it if you could break it down for me in a simple way.
