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
