A person who turns into a philosophical human rights activist while intoxicated. Though pretty normal while sober, usually this person would go on and on about their philosophical bullshit while under the influence. And God forbid if they detect another drunken Gandhi in the vicinity to discuss/argue with ... usually screws up the night for the Drunken Non-Gandhis who just want to enjoy their time.
Friend 1: Dude ... Sunny just had two beers ... I bet he's gonna turn into the Drunken Gandhi again.
Friend 2: Shit we should keep Jimmy away from him otherwise this night is fucked !
