A breh is
one who is always on the receiving
end, and, unlike a brah or a bro, never gives, contributes, or takes one for the
team.
Tom, Dick, and Harry are best
friends.
Tom is a brah, because he buys shit for Dick & Harry.
Dick is a bro, because even though he takes Tom's shit, he lets Tom & Harry chill in his pool.
Harry is a breh, because he takes Tom's shit, never brings his own
towel to Dick's pool, and has a curfew, which is
lame.
