russian wordplay, I guess? But these 2 words are phonetically different, so idk how this pun SCP works
It's true that it works only in writing (phonetically, those words have accent/stress on different syllables), and only in plural form.
But for some random scientist dude who barely knows russian, it might be enough to confuse the two.
I imagine the situation where someone stubbed the toe and screams "f*ck!", while the other person, knowing only technical side of the language, think "why is he suddenly screaming about copulation?".
It's slightly different here, but just an example that someone who just knows the language sometimes might make an absurd mistake, that someone who actually "speaks" that language would never imagine.
