Well,
Vodapas in a few different slavic tongues means water dog. But, water dog in those countries does not mean a dog for hunting water fowl, but is the name they give to sharks. In Croatia, and I'm sure in other Eastern European countries, they also use the name to refer to their military sailors.
As you may guess, I'm in the U.S. Navy. When my last ship pulled into Croatia me and my friends did what we always did. Found a nice bar off the beaten path as to get as far away from the other sailors and Marines as we could. They had two hot-as-hell barmaids and they kept calling us Vodapas. We finally broke through the language barrier and found out what it meant. I guess it just kind of stuck with me as I use the name anytime I have to create a user name or screen name.
The 77 obviously refers to the year of my birth. Oh, BTW if your ever looking for a great place to visit I highly recomend Rijeka, Croatia. Great place, nice people and it's hella cheap.
