Senpai`s tuna (Patreon)

In Russian, in jest, it is sometimes used to replace the word "dick" with the word "tuna," because the word tuna is consonant with the Russian daring name for dick - "хуец."  tuna - "тунец".

A slap in the face is called bream because they are also consonant. At present, in Russia, few people say a slap in the face, almost everyone in the conversation uses the phrase "give a bream" instead of the words "give a slap in the face."
