Erm, first WordCamp in Bucharest? I do believe myself, Joost, Kaspars Dambis, Frederick Townes, Scribu and a ton of other folk all attended a WordCamp in Bucharest in 2012 ;)

Here is some evidence :P

This may be the first "WordCamp Bucharest", but it's definitely not the first WordCamp in Bucharest (the first one, which we attended, was called WordCamp Romania).
