(noun) a day that starts out crappy but then spirals out of control, becoming crappier and crappier and crappier, as if the total decline of your life would never end.
A parking ticket, blown math quiz, and now my kid has scabies. I'm on a shit-day slalom.
On this day feel free to let your true feelings show, as no one can tell you not to. It’s a holiday. Post that person that fucked your gf, post that person who spit on your moms grave, post that person who didn’t give you $5 back after they said “I’ll pay you back tomorrow” 24 times.
Friend: “dude it’s National piece of shit day!”
Piece of shit: “what? No way!”
Friend: “yea, that’s why I posted your face on snap”
