addle : (verb) to confuse... but why would you use the word "addle" over "confuse"?

Addle is the more extreme version; it's when your mind becomes so perplexed that it turns to "liquid filth" and you're robbed of your ability to think any further.

The secondary definition is revealing: "goose egg addling" is a method to control the population of Canadian geese. They inject the egg with oil to prevent the embryo from developing, and it's done in a way to not arouse suspicion in the mother goose.

Not only does this double definition link mental disarray with physical spoilage, but it includes an external tamperer trying to go undetected.

Being addled is a confusion more than "I don't get it," it's paranoid and exhausted sense of, "a big conniving force has ruined my mind through overwhelm."

When your mind turns to mush after a 60 minute session on X, you've been addled.
