Well my real name is Daniel, and some time ago, some girl started calling me Dalle. (With the a from Oompa, and the e being something like the french sound for "eu")
Then a friend of mine was joking around, at a party, saying how much he loved me, and then he told everyone that he had made a new nickname for me, because it was much cuter (to show people how cute I was). The new nickname was Dallie
Unfortunately someone has already taken that nick, so without giving much thought to the fact that we might get mixed up, I chose Dalliez. ^^
