Yes, there are Russian. This is not a pure meme in his understanding. foundation here - that the word "жрать". There are three common words used in respect of the word is - жрать (Russian profanity) есть (general use) and кушать (cultural variant). As anything anywhere using the profanity (from cleaners to politicians) the meme is not here, this expression for sushi can be heard quite often. I don't know if there are any country in the world, in which the mprofanity is so often used in everyday life.
