This is kinda a weird thread, but somebody linked me some weird ancient /pol/ thread about black girls having diarrhea all the time because of genetics, so I was wondering about the different racial characteristics that are actually noticeable, aside from skin colour

I've never dated a black girl, but there's a black girl who lives in the flat opposite mine. So, the most obvious thing aside from the fact she's black is that she smells kinda bad. Pretty much every black person I've met has smelt like that. Not really overpowering, just kinda weird. I'm pretty convinced at this point that this is the same for most other black people, though I can't confirm it

The other thing is that she literally only pees once every two days. She told me that this is the same for a lot of other black people, and I didn't belive it at first but kinda confirmed it a while ago. Me and my gf, and her and her bf went to a festival couple years back and we were staying in one room to save money. I'm not kidding when I say we were drinking a shit ton of alcohol, and she didn't piss for almost two days. She could've easily passed for several months pregnant. It looked weird as fuck.
Don't know why she held on that long; guess she was shy because she got up at 3am when she thought everyone was asleep to use the toilet: it sounded like a fucking tsunami of piss for like four minutes straight. Didn't even flush before going back to bed. When I went to take a piss the next morning the toilet water was like a dark-orange colour and smelt of alcohol

I'm wondering if this applies to all black people or if she was just unhealthy? I don't really know many black people and I have no idea if this is true or not, I'm just wondering about the different ways in which white people and black people are different. Black anons welcome to contribute
And yes, this is a repost from /pol/ since I realise that was kinda the wrong place to post it
