It's called a lie bump due to the myth that these small bumps on the tongue are caused by telling a lie.
These bumps, medically known as transient lingual papillitis, are harmless and usually disappear within a few days without requiring treatment. The nickname "lie bumps" stuck around because of the old folk belief that a sudden appearance of these bumps indicated someone had been dishonest. Despite its popular name, there's absolutely no scientific evidence to support this claim. The true causes of transient lingual papillitis are varied and can include stress, irritation, certain foods, or even hormonal changes. So, while the name might be amusing, it's important to remember it's just a myth!
