A good example of this list comes from Bulgaria:
“Let a hungry Carpathian long-haired she-wolf blow your dick, fuck” (Gladna Karpatska valchitza s dalag kosam minet da ti prai deeba)
Who Said That? Bulgarians.
Dear God Why? Bulgarian cursing is based on a hybrid of nature references and non sequiturs. Most of the good ones read like Tourette’s syndrome Mad Libs. They still embrace common baselines, but the modifiers around it are what really shine.
Other helpful Bulgarian phrases:
“Your mother sucks bears in the forest” (Mayka ti duha na mechki v gorata)
“Fuck this tilted field” (Da eba taz kreeva neeva)
“You’re as ugly as a salad” (Grozna si kato salata)
