The plural is effluvia.I must be tweaking this morning; I was going to make a lame attempt at humor by saying “how this Gunjuice beats the pants off other effuviums” but when I went to look up the word “effuviums” it doesn’t exist. What comes up is the word “effluvium” with an “L” which basically means: an invisible emanation, especially: an offensive exhalation or smell. So did the word effuvium disappear from our language or is it just a typo? More importantly, “why do I give a f&*%”?
