What is the Russian word for pooh?

The most common Russian word for "pooh" is какашка (kаkаshka). It is a childish word, similar to "poo" in English.

Here are some other options, with varying degrees of formality and directness:

* Кал (kal) - This is a more formal and direct word for "feces."

* Говно (govno) - This is a very vulgar and offensive word for "shit."

* Дерьмо (der'mo) - Another vulgar word for "shit," though slightly less offensive than "говно."

It's important to be mindful of the context and audience when choosing which word to use. The informal "какашка" is generally safe for children, while the more formal "кал" is appropriate in medical or scientific contexts. The vulgar words "говно" and "дерьмо" should be avoided in polite company.
