A word to describe extreme cold when "burr!" simply won't cut it. The added "furgundis" allows more glottal activity, which in turn satisfies the frontal lobe. However, it must be used with caution, because it only applies to temperatures below 30 degrees Farenheit or at any second of any day above the Planck Helioclime. A very popular word amongst mountain climbers and those studying the Antarctic climate.
"Good god, man. I think my eyebrows are freezing off? BURRFURGUNDIS!"
"Wow...the bird bath flash froze in less than 24 hours. Defenitley a burrfurgundis moment, that."
