Answer:
National All-Truth Day
Explanation:
The first Thursday for every month will be celebrated in honoring the meaning of "ironic truth". To participate in this holiday, a tradition called "Writing between the Meanings" which is a document of all of the lies and truths you've said to people and self, which will be valuable in this holiday. You'll spend the whole day telling these lies and truths in different forms of irony. The whole point of National All-Truth Day is to express ones truths and lies, without being blunt about it.
A common ritual during this time would be called "the comic irony" which would take place with people you know (friends and family). The comic irony is a close relative to "two truths and a lie and sarcasm". The two truths you decide to tell about someone who is present can only be told through funny ironic sarcasm. And the lies you tell about yourself must only be a ironically morbid jokes. When the day is done and you have successfully gotten through of of the social activities with hurting others or your own feelings. Your family and friends will nickname you based on how quickly witty you are. (:
