His old nickname "9pashaebashu" is pronounced "ya pasha, yebashu". The number "9" looks similar to the Cyrillic letter "Я" ("Ya", which means "I" or "I am"). Pasha is his real name (a contraction of Pavel) and is what most Russian casters use. His nickname contains a Russian obscene word "yebashu", meaning "I'm playing f***ing hard"
