The song "Plastic Taste" by Joji is a reflection on the fear of vulnerability and the inability to express oneself. The first verse suggests that the narrator is hesitant to confront their feelings and express them directly to someone face-to-face, potentially out of fear of rejection or discomfort. Despite this fear, the narrator acknowledges that they are allowing precious moments to slip away.

The repeating phrase "excuse me for my plastic taste" could be interpreted in several ways. On one hand, plastic could refer to something being fake or artificial - in this case, the narrator could be saying that they feel insincere or inadequate in their attempts to express themselves. On the other hand, plastic could also refer to the literal taste in one's mouth, which could imply a sense of emptiness or a lack of substance.

The second verse reinforces these feelings of emptiness and avoidance, with the narrator repeating the same phrases and ultimately pushing the other person away. Overall, "Plastic Taste" seems to be grappling with the difficulty of confronting one's emotions and the fear of rejection or failure in doing so.
