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

Similar to "greening out" as a negative short term after-effect of smoking cannabis. However instead of vomiting you shit yourself. Browning out.

Side note: Most people who brown out deny it at all costs.
Conor: Damn boi, I was so high I think might have shat myself after getting off that train
Me: Woah I can't believe you just brown'd out for fuck sake Conor
Conor: No I didn't brown out I swear!
Everyone else: Did you hear Conor brown'd out at South Kensington Station

A lag in power getting to it's destination, where a black out would almost occure, but is averted at the last second. A dip in the ammount of power and quality being provided.
