Covid-flavor

Adjective:

To have a lack or absence of your sense of taste toward a food or drink item.
And it's comparison to a similar or different food or drink item. Or the inability to differentiate between flavors.

eating one skittle for its different flavor VS eating a whole handful of skittles and saying they taste the same, that'sjust that covid-flavor. Or the comparison of 1 color of fruit loop to another, you'll just got that covid-flavoring.
