The definition of which is: The act of cursing someone to be afflicted with phlegm; or, to be afflicted with phlegm, with or without moral judgment cast.
Use in sample sentences:
“I cast you into eternal phlegmnation! May Kimberly-Clark have mercy on your soul.”
“I suffer phlegmnation. You may wish to dunk yourself in hand sanitizer.”
A quick Google check prior to the entry being posted shows no instance of the word “phlegmnation,” and only on instance of “phlegm-nation,” being used similarly to “tarnation.” So I claim “phlegmnation” for all time, for use of all humankind. Please use it in good health, as ironic as that might sound.
