ETYMOLOGY
Neologism [new word, expression] following the 2022 Russian invasion of Ukraine.
Actually, just a blend of Russian + Z, using the Russian Z SYMBOL as substitute in Russian propaganda against the Russian invasion of Ukraine. At worse, it is a etymology parody for Russian.
[Katsap is a word used in a negative tone mainly by Ukrainians refering to Russians. The word originates from ‘goat’ (tsap), referring to the goatees once popular in Russia.]
