Scatterday

The day after one has part taken in the use of drugs, such as ecstacy, and are feeling "scattered". The individual spends the day on the couch as a space cadet, watching whatever is on tv, even if it is not interesting even in the slightest.

" what a night, dude are you coming to the beach today"?
" no chance man, todays scatterday"

Scatterday

n. Day of the week, commonly known as "Saturday," but much, much crazier.

Jane: "So, what did you do last weekend?"
Carla: "Well, Sunday was pretty boring, but the day before I had so much to do. I spent almost all day at the mall shopping, then saw a movie with John, and then went to an insane party. It was a total Scatterday."

Smatterday 

1) When you party too much and can't tell what happened on which day.
2) your day's run together because your so busy or drunk.

"My whole spring break was a smatterday."
"This conference has been a total smatterday."
