Sometimes i'll shit in the urinal
Okay, I know that people will probably think I am a complete douchebag for doing this, and even as an adult, I still do this sometimes. It's not random or anything though. Essentially, if something pisses me off at a store or something, and I'm able to stealthily crap in the urinal without people noticing, I'll do it.
If not, I'll just intentionally piss all over the floor by the urinal. Like just kinda spray some piss on the floor. Like there was once that the clerk gave me the wrong change at the grocery store. I was absolutely fuming and just fucking pissed off as hell, and then I went into the bathroom.
It just so happened that it was a one person bathroom, and there was a urinal in it along with the commode. So, since I had to take a crap anyways, I just said to myself, fuck this place I'm shitting in the urinal. I realize that people will probably think I'm a complete asshole for doing this, but I don't care. Honestly, doing this just makes me feel alive, and I love it. Like an act of revenge for random shit like getting the wrong change or whatever.
