Why is sticking your tongue out referred to as raspberries?

The expression "blowing raspberries" or simply "raspberries" doesn't actually refer to the fruit, but rather to the sound produced.

Here's why:

* The sound: When you stick your tongue out and blow air over it, it creates a series of small, rapid vibrations that resemble the sound of a raspberry, a small, red fruit with a bumpy surface.

* Origins: The term likely originated in the 19th century. While the exact origins are unclear, it's speculated that the sound might have been associated with the act of picking raspberries, where the fingers would brush against the bumpy surface of the fruit, creating a similar sound.

So, while the term "raspberry" might seem connected to the fruit, it actually refers to the sound produced by a specific action, which happens to resemble the sound of picking raspberries.
