The feeling of consuming something pleasing, expressed in a scribed sound effect.

History:
Originally heard in the game, "Team Fortress 2" as the Heavy class enjoys a sandvich (this is the correct spelling within TF2 due to the Heavy class' accent) all the while saying, "Nom nom nom..." while he consumes it to gain life.
"Nom nom nom... Sandvich is delicious!"

also, "Nom nom nom... Sandvich makes me strong." -Heavy

"Nom nom nom... Balony is perfect fuel for killing tiny cowards!!!" -Heavy

Can be used in an appropriate image file with only the caption, "Nom nom nom"
