YouTube Poop (also called YTP for short) is...well...kind of hard to define. It depends on the pooper, source, effects, intentions of the poop, and many other things. Without YouTube Poop, most of this Wiki would not exist. In fact, it might not have been created if it did not exist.
Poopisms are the keystones of making YouTube Poops.
The first YTP is considered to be (I'd Say He's Hot On Our Tail) aka (Super Mario Remix), which was not directly uploaded toYouTube. It was originally created and uploaded before YouTube existed. It was then re-uploaded on YouTube. Many people liked it, and started making their own poops. Then, someone uploaded clips from CD-i shames. Then, everyone was pooping Hotel Mario and Zelda. King Harkinian and Morshu. Became famous, after no one knew their names for over 10 years. After SpaDinner poops were growing old with the DINNER/Spaghetti jokes, people started using new sources and ways of editing. Like I do.
The old Spadinner style of pooping was very explicit. The people that made the spadinner stuff that got over 100,000 views probably were perverts and didn't care about community. They used Windows Movie Maker for a free fap clip creator. They tried to put bad stuff in it such as porn.
The nowadays style Youtube Pooping is more advanced and created mostly by young teen nerds or college graduates who finds more diverse Internet Memes funny. They were created with Sony Vegas or Premiere or any professional software like that. The new style had clean, more random humor like this wiki. Some people try to make it explicit by using word splicing and sex jokes. The new style has ear rape, better quality sources and a lot of moving animated images.
YouTube Poop is bigger than ever, and continues to grow, to Youtube's demise.
