You mean a 5th bottle of vodka, right? A 5th of a bottle of vodka is not much. That's 40% so 1/5 * 0.4 = 8%. That's like drinking a full bottle of wine, two bottles of cider or 4 pints of beer. You might get drunk but no fucking way you OD.
Most youngs need that amount to barely start getting tipsy...
That's not the part that was shamed, was it?
