Senseless Phagia

Senseless Phagia is when someone eats something because they can't tell what it is by using their five senses.

Senseless is when the senses aren't in use. Phagia means "consume."

If a person has no sense of smell or taste, so they eat dirt and thinks that it's chocolate, that qualifies, and they've committed geophagia.

This also applies when characters don't use their sense of sight while they're eating and pick up something gross and stick it in their mouths without even looking at it.

 * Minority Report has one, just after Anderton's eye replacement. The surgeon tells him that a sandwich and milk are in the fridge. Well, that much is true, but John's blind bumbling leads him to the rotten equivalents first.

The promgoers later remark that the punch tastes like piss, but don't seem to think it noteworthy enough to not drink the punch, apparently dismissing it as bad punch.

 * Inverted with Millennium, episode: Somehow, Satan Got Behind Me - Four demons, in their human forms, assemble in the predawn at a doughnut shop and reflect on the havoc they've wreaked on humanity. They, of course, mistreat the doughnut store clerk, who then urinates in their coffee, which they love.
 * One episode of Upright Citizens Brigade featured a sketch where one man claimed that color-blindness was the reason his niece couldn't tell the difference between a juicy, delicious apple and a raw, slimy pig anus. An audience member is incredulous of the claim, insisting there is something far more serious wrong with the girl if she really can't tell the difference. The first man offers him a chance to experience simulated color-blindness with a special pair of glasses and then offers him a choice of two clear ziploc bags (one with apples, the other with pig anuses):
