A lunch time holiday celebrating salsa and Paul Newman.
Mexicanaco Day is always celebrated with Tostitos, Paul Newmans Own Black Bean Salsa, a bowl, and friends.
It started when a bunch of high school friends who all decided that tomorrow they wanted Salsa. Eventually the tradition grew into a fiesta celebrating salsa at lunch time.

A 24-hour period in which you indulge yourself in complete gluttony, narcissism and sloth, in the manner of Eric Cartman on Comedy Central's South Park.
Guy1: Did you just pound down that entire box of Krispy Kremes?
Dude: Yep, I'm having a Cartman Day. A nap, then a tub of Ben and Jerrys is next, right after I get you to RESPECT MY AUTHORITAH!
Guy2: But... you're already a fatass.
Dude: Screw you guys -- I'm going home!

A day which consists of eating pesto pasta, watching youtube and playing fortnite. The intention is to be productive and work but realistically, it never happens. People who indulge in jason days are usually greek or have greek connections (i.e. a greek house mate)
Luke: Hi Jack, what is your plan for the day?
Jack: Alright Luke, probably going to have a jason day I haven't had pesto in a while.
