I have never heard of this term, but the definition that the other dude gave is totally and utterly wrong. 1st Bulgaria was under Ottoman rule during the 1700s and they had rebellions on their mind and not how to slap each other w/ their "wangs". 2nd, Bulgaria NEVER had dukes. The nobility is called in a very different way.
I don't know what that other dude was on when he wrote what Bulgarian Slap is but that's wrong...
