Also, cold piss isn't nearly as thirst quenching

Why couldn't they just use their own body heat?

Also, I'm kind of impressed they figured out how to eat it just enough to get to body temperature in a random microwave.

cos its made in AMERICAAAA RAAAAAAAAHH

it stands for teh land of the free

heat urine if you feel like it

Someone probably tried to heat "clean" urine to pass a drug test.

The war on drugs killed my convenience store burritos.

I can almost guarantee someone was trying to pass a drug test. Fake piss became easy to buy, and even include things like under-belt harnesses and fake penises. So even if someone is in the room watching you take the test, it still looks legit. So modern drug tests will also check to see if the urine is at (or at least very near) body temperature.

And this presents a problem with fake piss kits, because the surface of your skin doesn’t typically stay at body temperature; It’s usually anywhere from 90-95° instead of 98. Which means that even if you wear the belt pack all day, your body heat won’t be enough to warm the fake piss up enough.

So some people will resort to microwaving it just before they walk in. Get it to like 103° at the gas station across the street, (warm, but not enough to burn you when you wear it) so that by the time you walk across the street to take your drug test, it has cooled down to body temperature.

Drug tests.

Buy store-bought urine or bring someone else's for the test. It's still gotta be body temp when you use it. So you nuke it for a few seconds before you tape it to your leg on your way in.

A person was probably heating up some pee on the way to cheat a drug test. They have little thermometer strips on the side, like what you see on a fish tank, to help verify the sample wasn't brought in or tampered with.
