What does "manic" mean in behavior slang?

The term "manic" refers to being overexcited, hyperactive, or intensely energetic in a chaotic or uncontrolled way. The structure comes from the clinical term "mania," but in slang it is used loosely to describe heightened, erratic, or frantic behavior rather than a medical diagnosis. It is informal slang commonly used in everyday speech and online contexts to describe someone acting extremely energized, restless, or unhinged.
