Olde Nordic word meaning Spirit.

Used to describe terrifying spectres that walk the world, animated by forces unknown. Pale, moving in an odd and jerky manner, ambulatory, but dead inside, wights do not perceive the damage they do, but bring with them ruin nonetheless. They come, consume all arrayed against them, and repurpose the things they consume into terrible parodies of the things they were, often at terrible, terrible prices. Nothing is safe from them — all are consumed. Their coming is heralded by the malign call from the æther, whispers from malign networks such as The Dread Instagram and Planet That is Lonely by forces called “influencers”, who use the dark art of “hashtags” and “ess-ee-oh” to cause a horde of wights to converge, hollowing the soul of a place to a husk, and subsequently driving the prices of everything up. Nothing is safe.

Taken from the title character of Homestar Runner.com, "wight" is the pronunciation of "right" derrived from Homestar's speech impediment causing him to pronounce his R's as W's.
