The amalgam of particulates of god knows what one finds themselves covered in after a festival/concert/partying hard for straight days. Especially noticeable after tent hopping, passing out in the dirt, getting rained on, sleeping with random people, wash, rinse, repeat till partied out.
"what's this blue shit I'm covered in??". "...dude weve been tripping for days, that's rage dust!"
