The words "SNEFNU"/"SNAGNU" can be found in the reverse speech
(https://reversespeech.com/)
of several
high-ranking politicians, especially these days,
ones being obedient to it and other fighting against it;
obvious broad meaning:
SNEFNU or SNAGNU = (perverted) health (system);
it includes not only human/organ trafficking, adrenochrome etc., but all pharma, including vaccination terror
Especially, a certain high-ranking German politician seems to say it in reverse nearly always when saying "health" in forward.
