The Excrement Worm

When something reaches a certain level of excellence, it can then be called "The Cherry on Top".
This is not a fitness article, and it's plausible to imagine that on the slice of the most delicious cake, with the most desirable and perfect frosting, there at the top, shimmering in its translucent redness, is the most perfect and flavorful cherry of the century, balanced like a precious jewel: cultivated with all possible care and resources, harvested at the exact moment of ripeness, and placed there to crown an entire laborious culinary process!
The cherry doesn't need to do anything, as its mere existence is enough to brighten its surroundings and, without a doubt, make it desirable.

I don't know if this adjective, "cherry on top," is unique to Brazil, but there must be international equivalents to describe the excellence I'm trying to refer to.
The thing is, yesterday, after learning about something absolutely idiotic and absurd, I became aware of the repercussions of the episode, especially on social media, and I found it worthy of being classified as the extreme point—if it were good I would call it the "apex," but, since it's bad, I couldn't find an antonym of a word that could exactly define its magnitude—of degradation… so I thought about this "cherry on top" and started to imagine what could serve as its antithesis.

Just so you know, I considered things like "the larva in diarrhea," "the botfly larva in excrement," or "the little shit bug," but, in a middle ground, I ended up choosing the title of this text and occasionally thought about some of its attributes during the night:

É absolutely undesirable And, as if the putrid environment in which it dwells weren't enough, it's there because it was stealthily infiltrated or inadvertently swallowed up.
É imperceptible And if something destined for the toilets — flushes or landfills — remains motionless and its existence will never be recognized: it needs to move, make noise, and do strange things to become apparent.
The main action of his sordid existence is to indicate conditions such as disease, decay or death.

When we manage to link human beings to this lamentable term, we find people unaware of their abject condition and—lacking Cartesian notions—fighting to achieve an ever-increasing value of "y," even if negative, believing that through their fierce activism they will reach the status of "cherry on top"... and force the whole society to SWALLOW their rot!!!

AN EXAMPLE

The racial segregation created under the red pretext of "equality" is already fecal matter itself, but the term "cultural appropriation" indicates that the whole thing is already rotten... the "worms of the excrement" in this case are the people who, being black, recently classified the use of a turban — an object whose origin is oriental, from the Indian, Muslim and Arab world — by a white person (bald due to cancer) as "inappropriate cultural appropriation"!!!

Good heavens!!! If even the black people—and I am black, just so you know—aren't invented this whole thing, these premeditated spasms of feigned indignation only serve as proof that there is no intelligent life in these protests, only VERMIN FROM THE DUNG that like to live in feces (racial segregation) and who, using all their ignorance, imagine that they can become the "cherry on top"... except that their "y" has an inverted sign and leads them, and the whole society that swallows this politically correct nonsense, well beyond rock bottom.
Furthermore, how can one speak of "multiculturalism" (another fecal matter... very smelly!) and "inappropriate cultural appropriation" at the same time???

Feel free to cite more examples in the comments (which, by the way, will be moderated and, hopefully, even answered by me), as I'm sure there are plenty of examples.

Thank you for your attention.
