They’ll go snort an eight ball of cocaine and play in traffic...
I didn't find any meaning in reliable online dictionaries.
Is this synonymous with go play in traffic?
To go away and leave one alone because what is being done or said is very irritating.
Could you help me please?
The fuller text is:
But the only thing that frees us is that truth: You and I and everyone we know will die, and little to nothing that we do will ever matter on a cosmic scale. And while some people fear that this truth will liberate them from all responsibility, that they’ll go snort an eight ball of cocaine and play in traffic, the reality is that this truth scares them because it liberates them to responsibility. It means that there’s no reason to not love ourselves and one another. That there’s no reason to not treat ourselves and our planet with respect. That there’s no reason to not live every moment of our lives as though it were to be lived in eternal recurrence.
