I used the name breizzze for a long time just in general for email and when I started using chat rooms.
I can't remember where kia came from, but it just got added together and became kia.Breizzze
then when I decided I wanted to start dj-ing I kept it in full as "kia dot briezzze"
of course it got shortened and now i'm pretty much just kia said "key - ah" not "k - eye - ah"
