The verb, "addle," meaning to "make muddled or confused," can be used into only two contexts. This is from a linguistics prof who taught me years ago.
"You can," he said, "either addle eggs or you can addle brains. Nothing else."
"Ooh, ooh, ooh," a young coed in the front row cranked her arm for attention. "But professor, that's not true! I know it's not!"
