Have you ever wondered what the difference between a " Brah" and a "Bro" is? Does this not keep you up at night contemplating which one to use as a greeting or in a sentence? I grew up at the beach and around many a "surfer dude's" and this has always perplexed me. One day it's "What's up Brah" and the next day it's "Bro, you were totally shreddin the gnarl." After many a sleepless nights I had to find out what the difference was. So, I went to the source and interviewed a few local surfers - here is what I found out: Bro and Brah mean the same thing - Brother. "Bro" is more of a California surfer slang and "Brah" is Hawaiian. There is really no thought process behind how it is used - what ever comes out naturally. And then they told me about "Bro hoe's" that's a whole 'nother subject.
