An altered state of mind where the desire for sushi overwhelms all stimuli. The fog elevates one to a happy drowsy place where the only way to come back down is to give in to one's urge for sushi. Often precludes an all-you-can-eat sushi event and will peak after the meal only to slowly dissipate after.
If you suffer from the sushi fog and neglect to remedy the situation, excessive grumpiness, depression, negativity, aggressivity, despair and pain will follow.

"My bag? Myyy bag? Ohhh my bag! I don't know."
