It originated on Sesame Street. Cookie Monster, when he is devouring cookies, makes that sound.

It was mistranslated from, 'if you eat this crap, it will turn your body numb numb'. You think I'm joking? 🤣

Obviously someone was so annoyed with the nom nom sound they had to downvote this harmless post

Feels like a muppets thing…
Cookie Monster nom nom nom

when I was a kid the closest was Num Num
but memes (ideas) move thru Minds like bacteria thru bodies

I don't nom the answer

I don't know but if anyone makes sound while eating then I want to maintain minimum twenty feet distance 😁

It’s the sound of people eating with their mouth open.

I think it came from a comedy variety show like SNL, don't quote me though on that.

Some people trace it to the Cookie Monster

It's ridiculous

Not that I'm surprised, but some people [i]clearly[/i] have not embraced my thread in the lighthearted manner in which it was authored.

It's a joke, son! 😃

First I heard of it was on icanhazcheezburger.com

Some people can make a similar sound while going Mmmmm... At the same time they are eating.
Onomatopoeias usually don't sound like they are spelled but are more just a name of the sound.
