What it means if a girl calls you stupid boy?

Not enough information buddy
It can be anything. Depending on how she says it, her face expression, the context she says it in, time, who's around...

And girls generally should not be judged by the content of what they say anyway. Men use logic to communicate. Girls use emotions. So apparently you have caused her to feel emotions. Which ones... not enough information.

That you probably did or said something she didn't like

[RedStiletto88]

It means you’re annoying or did something that she thinks was stupid.

[Dragonstarterplus]

It means get the hell over it cause you're supposed to be 26

Is it "oh you stupid boy you 😘"
or
just "stupid boy 😠"

[Hassaniscool]
