Boys Eat Pineapple is an Internet catchphrase that originally stemmed from a Thai study that claimed pineapple juice freshens breath. In some areas, men believe that eating pineapple can make body odor more pleasant. In modern society, men are generally conscious of their image and breath, so eating pineapple has become a fad.

The catchphrase that all guys eat pineapple has been spoofed in different forms on some social media platforms. For example, some people converted the image and audio into a male-suggestive sexual behavior stunt. In addition, some netizens use the expression to show others how they identify.

In some Asian countries, pineapple is popularly recognized as a healthy food because it is extremely rich in nutrients. In these countries, pineapple is commonly used as a fruit or as a flavoring in cooking. It is therefore not surprising that guys consume pineapple to express concern for their health and personal image. In short, the fact that guys are eating pineapple is not only a sign that they are paying attention to their bodies, but also a sign of the times.
