I have been asked this question multiple times, and would always give a tl;dr version. Now I can finally tell the story in full.
So where did this obscure nickname come from? It all began a long time ago when I just started going to Klass English Language School back home in Riga. It’s wasn’t really me learning English, it was more of practicing it, so that I wouldn’t forget. Anyway, the real reason I got given this nickname is because of a peculiarity in pronouncing my name in English vs Russian. For English speakers, pronouncing my real name (Vadim) isn’t too hard, just a bit awkward as the name is unusual for this part of the world. For Russian speakers however, pronouncing my name naturally, in English, is very hard, as they are used to the Russian pronunciation. So as a result, they end up saying it with Russian pronunciation, and thus messing up the whole sentence due to the changes between Russian and English pronunciations. Thats when I realised that, I needed a solution for this.
