When you call in sick to work. But you really just want to take a day off and chill out.

Yeah, on Monday I took a mental health day and went on a daycation. It was so relaxing.

Mental Health Day 

A quasi-legitimate excuse to take a day off from school or work. Although the person who takes the day off claims he needs it to finish up some work and regain sanity from the rat race, he usually ends up sleeping in, masturbating and accomplishing less than nothing.

J.C. said he took a mental health day to catch up with work and relax, but instead, spent the whole day fantasizing about Jamie.

Mental Illness Day

This day celebrates the existence of Dreamgenders, Dreamsexuals, Animesexuals and Zoophiles.

Literally no one celebrates it.

Degenerate: "Hey lets celebrate Mental Illness Day!"

Sane Person: "what"

Degenerate: "I'm dreamgender"

Sane Person: "please go outside for once for gods sake"
