A Bromster is the combination of a Bro for life and a Master. So someone who is not only a dork who you can do the wildest shit with, but who also teaches and supports you.
"Thanks mate, you really know what to do!"
"No problem, remember I am not only your Bro, but also your Bromster. Call me when you need some advises again."
