requires creative thinking.

I would guess it's very close to the first thing that pops into the head of many a Russian speaker. А? Что? - Ничего. Желтые ботинки! Not to mention the frequent use in the classical literature, for the more high-minded. https://vk.com/topic-16292643_23535328

Fun fact: IBM 16xx computers from the early sixties did output "Ж" in place of an invalid character.

One can conclude that while technology comes and goes at an ever-increasing rate, Жопа is here to stay.

PS: "Жопа" in russian is "bums" or "ass" but means "shit happens".
