Started in the year 1990, Plurthday is a time to celebrate the wonders of plur. Friends come together and partake in the traditional Four Loko celebration in which all participants take turns throwing up on ferrets.
Angry light-shows begin at around midnight and by 4:00 am people are so drunk that they climb into their closets and yell at their little brothers because they're "trying to sleep."
Plurthday is sometimes mistaken for it's year round counterpart, the "Ferret Rager".
