As native Russian speaker, this is terribly rarely used in this full format (and it’s one among many), but genuine, I’ve heard it IRL.

“Тебя не ебёт, так не подмахивай”

This is highly and universally derogatory, you could expect to hear it from lowlife/criminal, which, unfortunately, is what most russians are lately, though. For russian nazi population, this implies that you are gay or a slut, depending on biological sex, and that’s close to your life worth nothing. For the rest, this is just something nazies would say to insult you.

The first part alone, though, is quite socially acceptable and overused. I guess, because it’s lost the whole lore behind it, and showing your knowledge of whence it came from kind of reveals that it’s not just an empty word, but you mean it.

I’m a bit hyperfocused on swearing, am I? Was one of my childhood’s special interests.

Honestly, “mind your beeswax” is also a rare gem, but not quite so rare.

Mighty Shai-hulud!

One surface, one edge, one gender

Actually I know a lab that ordered a large set of glassware from China directly from factory and erroneously received a different set of glassware. Turns out the same factory makes lab glassware and those kinky glass cocks and buttplugs to be filled with hot or cold water. What’s even funnier, the senior PI genuinely had no idea wtf that is and went ahead asking colleagues - people around the globe - what they think this stuff would mean, what weird technology is that.

Before you ask - I don’t know the name of the factory, but probably it’s easy enough to find on aliexpress, I’m into different stuff. Buying directly from manufacturer is better than buying from local reseller IMO. The best thing for a chemist in this category is probably buying lubricant components in moderate bulk and mixing them yourself so as not to worry about shelf life and be as allergen free as possible.

If the OP question is genuine - this thing is supposed to occasionally rotate around held by the neck, so the bottom has minimal footprint thus it does not hit anything. And this is the most stable and easy to manufacture shape for that.

Spent my first 3 years in academia doing exactly this. This is no 7.5 buffer. You’ve got suspension with zcp at around 7 probably.
