These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ear Rape being used in poops. It was originally regarded a staple in YTPs, but nowadays, opinions divide between whether its annoying and a tell-tale sign of a Spaghetti-Dinner poop or Actually Pretty Funny and most poopers just don't know how to use it properly.
Spaghetti-Dinner poops themselves. For some, they can be funny if done right, but to others they're a form of Seinfeld Is Unfunny or simply overdone. There's also a third camp who say that they can be done right, but it either takes quite a bit of effort or has to done in a way different from all the others.
Making sense vs not making sense. Making sense can mean many things, whether it be a plot with a Myth Arc or even just a Random Events Plot, and tell a story of some sort with it. It may also feature characters behaving in logical ways, whether all of them or just one or two. On the other end we reach True Art Is Incomprehensible territory, where there is no basic sense in it at all, and no plot at all. Which is preferred varies from pooper to pooper, with some trying to make arcs within their You Tube Poops and apply tropes to characters they use, and others simply aiming for as much nonsense as possible. It's a sliding scale for where each pooper lies, but there's no agreement which is better, and where it should be.
What defines YouTube Poop as a medium is also an issue of debate, and what it should mean as a whole. This especially applies to those who started from the beginning, where its overall aim was to drag users to something hat made no sense, and just confused and frustrated viewers looking for other videos, as a form of Dada. Others keep up the nonsense and prefer to amuse with it, taking it into Surreal Humor territory. A third don't enjoy being too nonsensical, but will still amuse with the basics of editing the videos to entertain, especially with characters being In Name Only versions of themselves.
Using Windows Movie Maker as the medium for making such videos due to the lack of features and effects other programs such as Adobe Premiere and Sony Vegas have.
There's also the opinion that proclaiming in a video's title or description that it's a Poop defeats the entire purpose of Pooping: subversion.
Dude, Not Funny!: People have gotten offended at the 9/11 jokes found in cartoonlover98's poops. More often than not they lampshade this, however.
However, 9/11 jokes date from even earlier in the CDI era of poop.
EmperorLemon has used similar jokes relating to the Concorde and Flight 370.
An old Dr. Rabbit poop features a video of the Concorde exploding.
There are also some AIDS and cancer jokes in some of the CDI poops.
Not to mention the constant squick in the more vulgar poops.
Ebola jokes joined the fray in October 2014.
Fanon: Some concepts not present in the source material have transcended the videos they originated from to become commonly accepted in almost any poop.
Hyrule's royal family living in Ludwig's Castle Hotel from Hotel Mario is one example. Some Poopers change the name on the castle or remove it, but others, even a few who use Sony Vegas and easily could, leave the name intact.
King Harkinian's "Munf Munf" cereal is another that has transcended to become fanon, as well as his "Dinner Blaster".
Hilarious in Hindsight: In No Swearing, ThePlamzJoker's meta-licious entry for The Clean Rosen Collab, Michael realizes he violated the collab's family-friendliness rules after he murders the man telling him to stop swearing. What makes this funny was that DaThings1's entry, The OUTing, was all about a teacher murdering her students.
Similarly, ChickenPika made two versions of his entry The Useless Outing, clean and dirty. Both involve a scene where Michael gets fed up at a student named Eileen and throws her out the window. In the clean version it says "She survived because this is a clean YTP", as apposed to the dirty one where it says "SHE FUCKING DIED".
Seinfeld Is Unfunny: Older-generation poops can be seen as this, particularly those that use what are now considered overused sources or memes. Repeated usage of "Mah boi", "Gay Luigi", etc. is now so old-hat that even most amateur poopers don't go for them anymore.
