means A mildly affectionate insult for someone socially clumsy or endearingly uncool, usually because they're too enthusiastic about something to notice how they look doing it.

from American slang from the mid-20th century, origin genuinely murky. One theory ties it to naval/teen slang where it was crude slang for 'penis' before softening into a general insult for a foolish person — similar to how 'dick' or 'putz' drifted the same path. By the 1960s-70s it had shed most of that edge on American school playgrounds, landing on its current sense: not stupid, just hapless, often worn as a badge of harmless uncoolness rather than a real jab.
