Ok, so let's you say you just snorted a bunch of (insert favorite drug to snort) and you feel a sneeze coming on. You do everything you can to prevent it but nothing is going to stop this category 5 sneeze. You put your hand up to your nose and ACHOO! you blow a metric fuckton of snot and drug into your hand...what do you do? Eat that shit? Snort your own snot back up into your nose hole? Or throw that nastiness away?
Boof it.
