interestingly enough the Brown Out is an output pin on a Microcontroller chip that indicates when power to the system is failing. e.g. when your TV tells you that the batteries in your remote are low it is because the Brown Out has flagged up a warning and the remote has transmitted that warning signal on to the TV

oh and it sounds like poo. haha

1. The act of defecating on oneself before making it completely to the toilet. Dirived from the term "Thrown out" (as in baseball), this term refers to the fact that one could not reach the toilet fast enough before they started shitting themeselves. Hence, the term "Brown out".
1. Yo, dog, get outta' the way, I'm bout to brown out
