Unicorn poo is at least sparkly.
Don't insult unicorn poo.
Unicorn doo is the most sinister of all doo, precisely for that reason.
Most doo is innocuous, matte, and earthen-colored. Aside from sometimes being particularly... 'fragrant', it doesn't actively do much to offend the senses. It generally isn't a problem so long as it's not directly in your path and you wind up stepping in it as a result.
Unicorn doo, however, sparkles and is brightly colored. You might mistake it for clay, until the odor hits you (which is a whole 'nother kind of pungent). You can't ignore it visually, either, unless it's in a very dark place.
As a result, I think my comparison is quite apt. This tweet is something that at first seems really appealing and shiny. Then you examine it a little closer and realize you're scrutinizing a pile of dung.
I rest my case.
