13 years-old 

First years of being a teen. A time in wich one is either in 7th or 8th grade. A very boring time to be a teenager. Parents often act as though you are still a little kid. Many are prone to being a prep. Others, a very little emo this happens toward more later in 13 age most only like the music. Most likely green day obbsessed (like mui).

Mom: MY little baby's 13 years-old!! it was only yesturday i was changing you diapers!!
13 year-old kid: Mom. please.
almost year later
Mom: HI sweety how was your day.
13 year-old kid (prep): Whatever mom.
or
Mom: hi sweety.
13 years-old kid (emo music liker): fine, hey can I go over to Melissa's later?
Mom: Sure.
13: Thanks!

I'm 13 years old and what is this? 

Another less funnier variation of the meme I'm 12 years old and what is this?

Said in forums that restricts the registration of people below 13. If you put the original version of the meme, which is: I'm 12 years old and what is this? Mods might think that you're ACTUALLY 12 years old and ban you because they're dumbass pricks, or just have a reason to ban you for the lulz.

Person 1: "I'm 12 years old and what is this?"

Dumbass Mod: "You're 12 years old? This forum is for ages 13 and up! *Bans Person 1*"

Another day:

Person 2: "I'm 12 years old and what is this?"

Dumbass Mod: O rly? I know that's a meme, but you piss me off and I have a reason to ban you. *Bans for the lulz*"

Yet another day:

Person 3: "I'm 13 years old and what is this?"

Dumbass mod: I thought the meme was "I'm 12 years old and what is this." What the fuck is going on?"

13 year old

A demographic that is often misunderstood and looked down upon due to stereotypes.
Like seriously, we're not that moody and not all of us are horny 24/7.

13 year olds are often considered to be the scum of the earth, but that's a very small portion.

13 year old

13 year olds are defined as creatures with raging hormones and lots of zits. they are often called dumb, naive and immature. tbh that's not entirely true not all of us are like that.

eg: "omg, I'd never date a 13 year old."
