"Veho" was derived from two different sources.
In the (good?) old days of arcade gaming, you could only have three-letter signatures on high-score charts. I used to sign in as "WAX". One day, a friend of mine bought a calculator with an alphanumeric screen and phonebook function. The screen was pretty basic, and the letters were pretty ugly, and you had to actually know what the thing was displaying to be able to read what the thing was displaying. "Wax" was a problem, because "X" looked like "H", and "W" didn't look like anything much, so one day somebody flipping through the phonebook read the name out as "Vaeh". The nickname lingered for a while, and then faded away. And there it would have ended, were it not for the second circumstance.
My real name is Vedran, and foreigners usually couldn't pronounce it, so I had to make a sort of non-phonetic, English-spelled version, which would be easier to pronounce, so I came up with "Veh-drun". This reached the ears of the friend with the calculator, who decided that it was my destiny to be known as "Veh". The "O" got attached somehow later on, and Veho I stayed.
