History and flag
This term was coined by FANDOM user Ariathatsme on May 26, 2021 as an addition to the Tavaline System. The flag was designed on the same date by the same user and the meaning is as follows: green and blue for innocence and old memories, grey to represent how much you've changed, red to represent childhood, and orange to represent a diary.

This term, however, was coined by a harmful user who faked systemhood, manipulated users, was exclusionist, and was endophobic. Because of this, people may be hesitant using this term, however it may be used in a reclaiming manner.

Etymology
The word deiboek is Frisian for "diary".
