Cold as Flugens
One of the dearest friends to my family has always said, “It’s cold as flugens!”, on particularly arctic days. So this morning, as I was letting Conan out at 6:30 a gust of wind blew into the house I immediately thought, “Flugens!”. But, what is a flugen(s)?

Thank you, internet.

Flugens — An intensive, chiefly southern. Hell, the dickens, tarnation, often in “cold as (blue) flugens.” Also, from 1830, “making money like flugens.” Also, flugens, furiously, in a rush. Other spellings: flugins, flujens, flujin. From “Dictionary of American Regional English,” Volume II, D-H, by Frederic G.
