Do you think others are pronouncing your username as you intended?
since I was curious how it sound my username in several languages... yes... definitely no surprise: it is corrected spelled/has always the same sound in any language I have heard/tried.
I made a test with google
https://translate.google.it/?sl=it&tl=en&text=bitbollo&op=translate and it sound more or less correctly in any language (ok not really perfect in Bulgarian or Nepalese but this is a good starting point)!
It's funny (at least to me) that in any language you want to curse me ... it will always sound the same
