I get asked this question quite a bit actually.
Haoleb is broken down into two parts Haole, which is a name that locals will call a tourist or someone from the mainland here in hawaii. Basically anyone who is white. To some people its kind of a racist term but I was born and raised here and dont feel that way. And the second part the "b" which is the first letter of my first name (and last for that matter) Which is Brandon. Hence, Haoleb. Quite often gets misspelled when others try and write it to. I would say about 80% of the time.
