I was told that a long time ago Ukrainian swearing was based primarily around act of defecation and ass (срака) itself. But nowadays you can rarely hear that. Instead cunt (пизда), dick (хуй) and their derivatives are used all over the place.
Are there any studies exist on what was a causethe reason / push for moving towards genital based swearing? Was that indeed Russian influence? Or maybe it happened as a result of internal changes in Ukrainian society (for example, Ukrainians nowadays are far less religious than before)?
