My favourite: "Then one day you’ll hear Bulgarian-ized English pass through you’re lips. Your heart will stop. You’d never have thought that was possible." :D
I perfectly understand you. Don't you develop some sort of terminology that only you and your fellow expats can understand? Something like calling all coins "stinky" (from stotinki) or something like that?
Because we "fail-vame" and "pass-vame" exams, we "retake-vame" courses and the train has Verspaetung (delay in German). Furthermore, today I have to do two "reading-a". Empty bottles are called Pfand (deposit in German - the money you get back after returning the bottle). Isn't mixing languages your favourite hobby now that you've been for quite some time in BG? :)
