Der, obviously it is. According to Google and Wikipedia, it dam well is! So therefor and thus, I concur.
"The term "foodgasm" is used to spectacularize moments of eating pleasure; indeed it stimulates the nerves, the senses, and the pleasure center of the brain." (Wiki)
The neologism of "food" and "orgasm" is like when Pinky and The Brain, "by the dawning of the sun" ... they'll take over the wor...d.
Anyway, this has actually got nothing to do with food porn which is more like the over-viewed attraction we would have by just walking by, stopping, staring, glaring etc.
Foodgasm refers to the pleasure we would get by physically enjoying each morsel we devour one, small (or big) bite at a time. Of course, we all have our own way to enjoy the divinity of a dish, the spoon, the forking of it all. No one judges here. The final outcome is hitting the pleasure centres at all costs.
Now that's sweet.
