Portmonteau of "Bro" and "Obligation". If you are bros with someone, no matter how shitty his band is or how mind-numbing his poetry is, you are obligated to be his number one fan. Or, you know, decide to take some time off from each other while you consider new bros that might be a better match for each of you.
