A loud and sometimes annoying sound made when eating. It is also made when a large person sees food and runs over, stuffs it in their mouth and devours it like it was fancy food being eaten by a rich person.
Friend: Is that a raccoon in my trash?

Me: I dont know.

Friend: Oh my god it is.

Raccoon: OM NOM NOM

First person onomatopoeia for eating with enthusiasm.
First person: *Om nom noms* leaf cupcake.
