Savorgasm
n. The ecstatic delight experienced when the taste and fragrance of particularly delicious food reaches the neural receptors in the brain resulting in a spiritual transportation to another place and time. Characterized, by an upward rolling and crossing of the eyes, a low, involuntary moan, and generally followed by an interjection such as "Oh God!".
With the first bite of "The Best Pesto In The World", she had an instant savorgasm.
