So, basic swearwords in Russian are the same as in English. “Cunt” being the most explicit one.
That’s why the word for a great fuck-up (cluster-fuck) stems from it.
Pizda – > Pizdets
Pizdets is an apocalyptic fuck-up, something bad on galactic scale. Well, what’s going in Russia is usually a pezdets.
And the world also sounds a bit like Pesets
And pesets is an arctic fox.
That’s why, when something bad happens, you can literally say: “Small white furry animal has visited me” – and everybody would understand.
And there are tons of puns on this account. Because “full polar fox” means at the same time “fat fox” and “total fuck-up”. So you can just post a picture of chubby fox and be understood.
