545 – 8 Slang Words Meaning Stupid

MichaelADIdioms Leave a Comment

Today I’m going to show you 8 different slang words that you can use to say that a person is stupid. And let me say this very clearly. I’m not talking about people who have learning disabilities or anything like that. When I say stupid here I’m referring to people whose behavior is obviously foolish. And to me that signifies that the person is stupid.
Here are the example sentences. To get the details of this English lesson, you need to listen to the podcast or check the transcript for the details.

  • The first word is airhead. Air…head. You can imagine that this kind of person has only air in their head and no brains. He’s an airhead.
  • Next is a birdbrain. Think about how small a bird’s brain is. A person who is a birdbrain has a very small brain. He’s a birdbrain.
  • Next up is a bonehead. The bone in your head is called the skull. Well, if you only had bone in your head instead of a skull and a brain you would be a bonehead, and that would make you very stupid. He’s a bonehead.
  • The next word is dimwit. Dim means not bright. For example, compared to the lights in an office or a school, a candle is dim. So dim means a low level of light. Well, wit means intelligence. If we put them together, dim means low level… wit means intelligence…so a dimwit is a person with a low level of intelligence. That guy is a dimwit.
  • Next is knucklehead. Your knuckle is the place where your fingers meet the back of your hand and the bone is very close to the skin. But basically, in your knuckle it’s just skin and bone, so we use that image and we say that the person is a knucklehead. He’s a knucklehead.
  • Next up is peabrain. A pea a very tiny, round, green vegetable, so we imagine that a person who is stupid must have a pea for a brain. That guy is a peabrain.
  • The next word is pinhead. A pin is a very sharp, thin, tiny piece of metal. Very tiny. Like a very tiny brain. He’s a pinhead!
  • The last one for today and one of my favorite expressions is dumb ass. Now I have to warn you, the word ass is a slang word which means the part of your body where you sit. But before ass picked up that meaning, ass meant donkey, and a donkey is not a very intelligent animal… or so they say. So a dumb ass is a not very intelligent animal that is not intelligent. He’s a dumb ass.
