Bro-seiden

The ultimate overlord of the Brocean and thusly, all bros. Whenever a new characteristic of bro-dom is added (ie. hats with pre-frayed brims, Jack Johnson, Natural Ice) it must first be cleared by Bro-seiden.

"Dude, isn't this Super-chill-lax Band awesome?!" - Bro #1
"I don't know bro, we better wait to hear from Bro-seiden." - Bro #2
