When one farts/sharts so loud in the morning that it wakes up your wife or significant other next to you.
After having a late night burrito, I got gas so bad that this morning I farted so loud, that I woke up my wife next to me. Thus I created a Brown Note Alarm Clock. Needless to say she was not happy with the accidental Dutch Oven that occurred as well. See also Dutch Oven.
A fart so loud it wakes up the farter and/or their bedfellow(s).
I would have been late for work this morning, but Cynthia's brown alarm woke me up in time.
