The Brown Beacon is when your bowels have begun a pre-launch sequence and you have only a few minutes to get to a toilet before you shit your pants.
I was in the store picking up a 24 pack of The Beast and suddenly I felt the Brown Beacon. As luck would have it, once I found the shabby bathroom the toilet looked like someone had sharted on it and the stall door wouldn't lock and I had to out-wait a Stall Stalker.
