Honestly, I get tired of that term as it relates to certain things.
Someone takes a pile of poop and smears it in your face, there's nothing "subjectively smelly and gross" about it.
It's a pile of shit. It came out of someone or something's ass, and now it's in your face. You can debate the merits of it ... pretend it smells like a bouquet of roses and use cliches like "One man's lump of shit in the face is another man's treasure." But it just smells bad, and it's really gross ... and you should really get a towel or something really fast and wipe it off. Even by the most liberal of standards of the word, I just don't see how one could call it "pleasant."
