Fatuity

Fatuity: Noun:Ā something foolish or stupid :Ā a foolish or stupid quality

From the short story “The Yellow Wallpaper” by Charlotte PerkinsĀ Gilman. “Looked at one way each breadth stands alone,Ā theĀ bloated curves andĀ flourishesĀ — a kind of Ā “Debased Romanesque” andĀ deliriumĀ tremens — go waddling up and down in isolatedĀ columnsĀ of fatuity.”

I now understand that she was saying that the lines in the wallpaper were moving up and down andĀ basicallyĀ all over the wall in a stupid or foolish way. Sort of like they had a violentĀ deliriumĀ and shook allover with tremors thereby it looked like it was all over the place.
