Derived from the latin word Broseph, a bseph is more than just your bro. A bseph will be there for you at all times no matter the circumstances. It is as strong as the relationship can get between two heterosexual men.
Bseph One: Bseph, I need a place to crash for the night.
Bseph Two: No worries Bseph. Sleep in my bed. I'll sleep at my girlfriend's.
