TikTok seems to be abnormally focused on what the lion does or does not concern itself with these days.

It's become a meme to post about the lion or lioness — meaning yourself — and what does or does not concern them. Most of the time, in the TikTok trend, the lion's (or lioness') concerns are either relatively trivial or outside what you might expect from a so-called grindset online figure who'd actually post this sort of thing in earnest. So the lion may not be concerned with the effects of energy drinks, or it may be concerned with their anxious thoughts.
