Man, you’re going to grind me down into actually answering this instead of posting an immature gif?
Okay, let’s say you’re a youtube personality in the earlier days, who gets paid by subscriber and views, and know that a video where you dook on a friend will be a popular video that will likely get a lot of hits (because, tons of people with an immature sense of humor)… Make sense now?
Also, I can think of reasons “other than porn” where you’d crap on someone. I’ve got an a-hole neighbor who desperately deserves to be crapped on (because that would likely be a physical embodiment of how he treats others). What I don’t get it how it would be a porn thing. But, I’m content to leave it at “to each their own, as long as everyone’s a consenting adult…”.
