Why the name Bratishlava?

Why the name Bratishlava?
It started as an inside joke with friends, we were joking around and someone said "Ik ben Bartolemush van Bratislava". That rougly translates to "I am Bartolemush from Bratislava". So me and an other friend made accounts on an unknown game, he was called Bartolemush and we thought that Bratis-h-lava was spelled in the right way so we went with that.
Since then I've been using it for a long time, and people STILL KEEP FUCKING ASKING IF I'M FROM SLOVAKIA GODDAMMIT.
