I've done it, it's quite alright for you.
It's piss! Hot, steaming, human piss!
Now to be fair the piss I drank was neither hot nor steaming. A scientist was doing a presentation in our school and you had to pick 1 of 3 and guess which was one the piss. I not only did the sample but then guzzled another cup full, much to the disgust of those around me.
Sounds like a right kinky school.
