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.
