What the hell?
Let me tell you my story.
I once had a bottle. It contained my piss, loads of months old spittle and old ash from smoking weed. Please don't ask me why and how that bottle happened. I was young.
So, I woke up in the middle of the night, still super high and damn thirsty, grabbing the wrong bottle and took a big and nice sip of it.
As I realized what just fucking happened and the shock/shame went through my soul and body, I sprinted into the bathroom, spit that stuff out, grabbed Shampoo and squeezed it into my mouth, because I thought I need SOMETHING to "clean" it.
That stuff was even WORSE than the already disgusting piss mix from before! I barely could hold it in and not throwing up. It was probably the most disgusting and evil taste I've ever experienced.
So yeah, never eat Shampoo!
