Sinday 

the day you should be in church but you're secretly home smoking bud and chilling with some champagne

"Dude, I can't wait to see you this Sinday, I've got some killer buds that will make you feel religious!"

Sinday 

A new day to fall between Saturday and Sunday. Extending the week to 8 days a week.

The day would be used to take part in all those things that you really don't have time for at the weekend. Every slobbish, bad for you, hedonistic thing that you wish you could do but because the weekend is so short you don't have time to recuperate.

Sunday is now just like any other day. We need another day in the weekend to make up for it. Bring on Sinday!

What are you doing this Sinday? Fancy going on an all day bender?

Am not getting out of bed today, I can do the chores on Sunday. Today is Sinday!

sinday school 

a place of worship where little kids or young teenagers go because their parents force them; commonly known as "sundayschool", but instead of staying for worship, such kids leave to sneak off with their boyfriend/girlfriends for a quicky at the near by gas station/starbucks/petes coffee/or any vacant restroom.

Becky: GURL, i cant wait for sunday!
Lisa: Why?
Becky: cuz Johnny's gonna be there! and he just broke up with his skank girlfriend!

Lisa: OOO GURL YOU BETTER TAP THAT AT SINDAY SCHOOL!

Spite Monkey Sunday 

Spite Monkey Sunday is that day of the week when all the brain dead little losers try to get definitions accepted by Urban Dictionary. They try to get a flattering definition accepted, of themselves if they haven't got any friends, or of some female if they think it will help them get into her knickers. Why? Usually because they’re back at school on Monday and are trying to make themselves look good, the poor little winkies. Then the unthinkable happens, they’re definition is rejected because it doesn’t conform to the rules laid down by Urban Dictionary. Oh Calamity! So the silly little wank biscuits throw a hissy fit, go into a session to vote on the inclusion of new words and reject everything without bothering to read it. Then comes Monday and these sad little gleets go back to school and bother the human race somewhat less than they do at weekends.

“Couldn’t get a thing accepted on Urban Dictionary, it was Spite Monkey Sunday.”

Sod All Sunday 

Definition---
An entire Sunday day which passes where absolutely nothing transpires; A miscreant day which you will never remember; A Sunday which is sullied away to pyjama wearing and not bothering to lift ones arse away from the sofa for more than a toilet visit. The phone does not ring and your mobile is not blessed with anything other than a full battery.

Example---
Dan: How was your Sunday? Get up to much?
Garath: Good mate cheers, I had a sod all Sunday.

sunday curse 

having school or work on monday, and not being able to get to sleep on sunday.

usually it carries over, and makes it really easy to get to sleep on monday night, although sometimes a little too early

I got 3 fuckin hours of sleep last night because of the damn sunday curse
