A day of historical significance, where 2PM's ex-leadja, Jay Park, posted a cover through youtube after almost half a year of absence.
Girl2:I KNOW, I JUST WANTED TO FUCK HIM ALL NIGHT LONG.
Girl3: jaysus bless this jayday
Relating to a day taken off from work when perhaps one could actually go into work if one had the desire to do so.
(more covert and cooler than a mental health day)
Origin: A Shortening of the Hebrew name Jeremy, combined with the word day meaning "the interval of light between two successive nights; the time between sunrise and sunset:" Coined as a popular phrase by Alan & Kim in 2009.
Kim: I don't know, it's been a really stressful week, I may take a Jay Day"
Kim: Is your brother out sick today?
Alan: Yeah, he's out, but I think he's just taking a Jay Day.
