They're not saying they want juice coming out of an ass when they call an ass juicy... It's meant to describe something that looks appetizing, like a juicy grape...
And that ass is very defined/toned, I would not classify that as an "absolutely normal ass." I don't think it's thicc, per se, but it is a very attractive butt (and I say that as a straight guy). I do agree "thicc" is highly overused, as it should be describing something or someone that is actually a bit fatty/curvy/voluptuous, versus an athletically toned piece of anatomy.
We've had failing infrastructure for.... Idk... Like 40+ years now? The wealth class gives zero fucks, it isn't impacting their homes or neighborhoods. Yet... We keep voting them in as their literal shit floods our homes.
