What would happen if somebody were to drink the orange juice mixed with dubra thats been sitting behind my bed?

Ok so a bottle i mixed with OJ and Dubra has been sitting behind my bed for atleast 2 months now i had it there to keep it hidden from my parents but in doing so i completely forgot about it myself.I would obviously never drink it and i'm not implying i ever would under any given cirstance. I'm just wondering what you suggest would happen given someone was drinking from that gross bottle thats lingered behind my bed haha. I'm guessing it's got all kinds of bacteria and such and my hypothesis is that someone would get really drunk trip from whatever else is in there,and die haha.This isn't a legitimate or serious question im just curious what you think would realistically happen.
