In American slang, the term “trippin’” is often used to describe someone who is acting irrationally, overly dramatic, or out of control. It can be used to express that someone is overreacting, being unreasonable, or acting in a way that doesn’t make sense. For example, if someone is getting upset over a small issue, you might say, “You’re trippin’.”
The term can also be used in a more lighthearted or playful context, such as when someone is jokingly exaggerating their actions or emotions. Additionally, “trippin’” can sometimes be associated with being under the influence of drugs, particularly psychedelics, as it refers to the altered state of perception one might experience.
The exact meaning depends on context, but it generally suggests that someone is not being rational or in control.
