An amazing expression my lovely wife uses to describe both the act of dimming a screen or her own intellectual capacity

Umbright 

A last name of germanic origin (from Umbricht) with the amazing ability to impart hyper-intelligence to the fourth born child in a family. Tragically, this magical gift relegates the first three children to substandard intelligence.

The three eldest Umbright children gaped in slack-jawed, simple-minded awe at their youngest sibling.

Unright 

Unright it a synonym of badly and is derived from the term "not right"
It should not be mistaken with its homophone unwrite.

This term was first made famous on Instagram by poet @thoughts_by_steve in his epic poem "Sentenced to write about Humor" written for Poetry Battles 24

About humor that’s spelt somehow unright.
