stoner's night
An evening chiefly designated for, and defined by the recreational consumption of cannabis. The night may entail other pleasures such as those of the flesh, entertainment (television or otherwise), and/or food/candy, but these are all secondary to the enjoyment of cannabis.
I've picked up several pre-rolls, chosen a film to enjoy, and stocked the kitchen with chilled natty wine, snacks, candy, and pizza. It's going to be a classic stoner's night.
