People sometimes act in silly or confusing ways. We might see someone do something that doesn’t make sense, and it’s hard to explain why. Instead of saying, “That was dumb,” people often use similes. A simile is a way to compare two things using the words “like” or “as.” These phrases help describe something in a fun or clear way.
In this article, we will look at similes that describe someone acting in a not-so-smart way. These comparisons can be funny, silly, or just easy to understand. They are used in everyday conversations, especially when someone wants to make a joke or say something without being too harsh. Let’s explore some similes that people use to talk about dumb actions or ideas.
