Brownlining is fishing discolored water for fish most anglers avoid, and are not typically eaten. Muddy creeks filled with farm effluent and debris, urban rivers choked by trash and runoff from streets are brownline waterways.
The state and level of intoxication required to brownout for a long period of time, without blacking out, or sobering up; at the perfect level of drunk all night.
Man the party last night was so lit, I was brownlining for the entire night.
