Guys, When a guy says shut up to a girl, what does it mean?

[AleDeEurope]

It means exactly what he said, shut up. She may think you're annoying and couldn't take it anymore, that's why he said shut up even though you were speaking not too loudly.

What's for sure is that he didn't wanna listen to you talk.

[FrugalMoogle]

Whatever you're saying or talking about has gone beyond the point of being an annoyance and that person actually thinks you should just be silent around them for awhile.

It just means be quiet. It means the girl is annoying him in some way.

[Anonymous]

It means he has no respect for you. Whether it was a transient or eternal disrespect is up for debate. Is this guy a lover, close friend or just an acquaintance?

I would never say that to a woman.

It means be quiet
