What do you not know and couldn't care less that you don't?

I think the first two are the same - synonym names for the same animal (also an 'ass' in biblical parlance), the second two are the same way - different names for the same animal, but the two groups differ in that one (I _think_ the second group) is a sterile hybrid animal resulting as a mating between a horse and one of the first group. not that you wanted to know but I looked it up once and I feel weirdly smug that it might be even slightly useful in a random context so I have to regurgitate. for things I care nothing about - modern gen z slang. skibidi 6/7 something rizz. it's vaguely interesting in social and linguistic ways, but learning it seems pointless and possibly even intrusive - they came up with it so I wouldn't know wtf they're on about.

I could find out who that Taylor Swift fellow that everyone keeps talking about is but I don't really care.
