Urban dictionary is not a real dictionary, so, no. And, frankly, you don't want that "meaning" added. It is not positive.
Gich is an excellent pronounceable brandable. What I like:
1. all western premium letters
2. only 3 sounds
3. easy and single way to pronounce in English (the same is true for German and French, although different pronunciation).
It is definitely $x,xxx name.
