The day that comes after Friday and before Sunday were devoted drinkers gather for kegs of natural light from 10:30am-6pm then followed by more drinking, music ranging from techno to classic sing along music and good times

... not for those who have weak livers....
Bob,"ugh such a long week I can't wait to drink all day at naturday"

Nick" for sure bro I'm going to rage all day and drink out of kegs all day long"

it's a day of the week, sometime between wednesday and saturday, but not necessarily thursday or friday. it changes, and it's not every week. it doesn't have anything to do with drinking light beer.
cody:hey yona, sup?
yona: not much, you?
cody: well, last naturday, i beat fallout 3
yona: naturday? what the hell?
cody: yeah, naturday, it's a day between wednesday and friday
