omnomnomapoeia 

The formation of a word iminating the sound one makes when eating, such as om nom nom, crunch, slurp, chomp, etc. A portmandeau of om nom nom and onomatopoeia.

"While making dinner, I decided to sample the delicious feast I was preparing. Pleased with the results, I mouthed aloud an enthusiastic 'OM NOM NOM NOM NOM NOM NOM.' The others quickly dashed into the kitchen and queried as to just what in the hell the sound they heard was. 'An omnomnomapoeia,' I replied. 'An omnomnomapoeia?' she laughed, 'isn't that a sound you make whilst eating?' Proudly, I told her 'yes, that is correct.'"

Omnomnomatopoeia 

Any word whose phonetic structure, whether through auditory impression or physical shaping of the mouth when saying, evokes imagery similar to the meaning of the word itself, where said meaning is food or eating related.

Any word that sounds the way what it means tastes or feels in the mouth. A taste/texture-specific version of onomatopoeia.

See: omnomonym

An example of an Omnomnomatopoeia could be that "zesty" sounds the way zesty things taste. Also consider chewy, crunchy, delicious, savory, pucker, sauerkraut, munch, slurp, etc.

Omnomnomavore 

Person/animal who likes food.

Brittany was ravenous. She wolfed down the salad, then the appetizers, then the entrees, then the dessert, then the horses in the barn, and, finally, the cows in the meadow. She sure was a gold star omnomnomavore.
