Why do some girls act so stupid?

She doesn't want to get the label, "Nerd", "dork", or "geek" so she acts stupid so people won't know she's smart.  I do that all the time.  I am a smart, nice girl and it's just like that saying with guys, "nice guys finish last."  The same is true with girls.  Only the stupid, flirty, gorgeous girls have lots of dates.  Us smart, nice, average looking girls have a hard time so we act dumb hoping to get the guys to notice us.

Excuse my language but:\n\nYou can officially be a d*ck when a girl treats you like sh*t and acts like a b*tch. I recommend being a d*ck professionally, by telling her the truth about her stupidity if she acts stupid, undenilable proof that what she did or is doing is wrong and show her you were trying to be a gentleman up till that point. Don't let b*tches push you around. Be a good guy up until they give you sh*t for no reason. Since women are supposityly more mature than men, they have no business acting immature. And so when they do, call them out on it which only a jerk does that. But they deserve it. Otherwise, who else is gonna teach them that it's not always true that there sh*t don't stank?

The same reason girls act phony to guys.They're insecure and want the opposite sex to like them, and they don't think they have anything to offer. It's more complex than that, and there are more reasons, but that's the most obvious one.

When a girl is unattractive or otherwise undesirable, a guy will act funny and dis her around his friends.  He's trying to give the perception that it's "nothing serious, I'm just using her" so that his friends won't annoy him about you.\n\nDon't worry, he's just protecting himself and you from ridicule.

Teenage girls do it everyday by acting like their stupid when they really aren't. Acting like they don't get the punchline of a joke just so everyone will pay attention to them. It's really annoying when my daughter does this just to get a laugh out of someone. Just today she acted as if she didn't know the golf cart took gas. She knew good and well that it did!!!

Because girls rarely experience that. Just back up what you are saying with actions and then they will know that you are for real.
