look up any word, like swag:
The act of posting inane status updates, tweets, etc. to liven up an otherwise mundane existence.
1) " So happy about tomorrow!"
* This mundinanity forces readers to inquire to poster, giving poster a positive reinforcement to do it again.
2) " Having chicken and biscuits! Yum!"
* Obvious mundinanity, the most exciting thing in your life is chicken and biscuits?!?
