taste twitch
The twitching or slight muscle spasms that are often associated with consuming a normal yet slightly off flavored food (probably sour candy) or drink. because the reactions are few and far between, it can be hard to determine the exact flavors that cause the reaction, and it may only effect certain individuals.
I was drinking my favorite snapple when i noticed the flavor was slightly off, after swallowing, i experienced taste twitch throughout my torso.
