(n): A portmanteau of 'bro' and 'crusader'. One who spreads the way of How I Met Your Mother, and (by extension) Barney Stinson, to the unenlightened.
My bro introduced all his hallmates to HIMYM this weekend by showing them the first few episodes. They're completely hooked. He is truly a brosader for the cause of righteousness.
