Why do teenage guys act so stupid sometimes?

all guys are stupid. they don't get better as they get older either... but for some reason they are worth it anyways.

because some men are idiots and don't know any better.

because they're immature and horny and not very smart and lazy and they wanna be like peter pan and never grow up.\nand i hope all men don't hate me for answering like this, because not ALL men are like that, but a bunch are.

it's coz they hit puberty first.\n\nBut mostly nowadays, girls wanna show off and make themselves seem older, so they do stupid things.\n\nAlot of it is peer pressure too.  Girls don't wanna feel like they're being left out or excluded, so they do these things.  \nBut about 70% of girls/teens who brag about acting older/drinking/using drugs/having sex are lying because they wanna fit in and sound 'big'

They do it to get attention.  They are also trying to get you to respond/argue, so that they can laugh at you.  It could also be because they don't know you, so they figured acting stupid is ok.  Some people's "stupid questions" may actually be real ones.  That is just what I think.

Guys show their parts too. People that do that are ignorant, they have no respect for themselves or for other people. people that do that do it because they think it's cool and it is because they lack confidence and they know that it will bring on the attention of others. They don't care about the consequences.

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.

All 15 year old boys act weired and even when they grow up men tend to get weired when they are with a group of guys.  What you are experiencing is perfectly normal.  You have nothing to worry about.

Guys are not confusing. We are TERRIFIED of making a mistake. So we do nothing, say nothing. Better to be safe.\n\nBlame it on society. We are the breadwinners, the soldiers of the family, the protectors, the primary money makers.\n\nNow, everyone tells us this - but NO ONE tells us how to do all these things! So we stumble along in life, learning on our own these things. Does not build "character," just makes us an emotional wreck. That is why you read about so many guys "loosing it" and ending up doing amazingly stupid things.\n\nOnce we figure it all out, we make great companions. But it just takes a long time. Be patient, be kind, and it all works out in the end.

There are so many answers to your question. Beside the reasons that you have mentioned I guess they want to prove to the world that they are grown. The teenage years are considered the rebellious age, so I imagine acting out in the manner that you have described is not unique to America but any where teenagers are.

Guys are not complicated, we just get caught up in which lie we told you girls and then get flustered.

cause they think if they tell a girl how they realy feel then they will think hes a punk for it or his friends might find out and make fun of him.... guys are self-centered and wont tell a girl how he feels.
