A little pest who likes to burst into your room while your doing homework, or playing on your phone. They like to hit you, then like a little bitch, they tell your parents when you hit back. In other words...they are annoying. They are so annoying they make you feel like banging your head against the wall so hard you lose all your brain cells.

You: *on your phone*

Younger sibling: *bursting into your room and runs up to you* Hey!

You: Go away.

Younger sibling: No! *Slaps*

You: *Slaps back*

Younger sibling: ....MOooOOoOoM *ugly sobs*

You: GODDAMNIT *bangs head against the wall*

Soul Sibling

A friend who you are very close to and see and talk to almost everyday; it's as if they were your brother or sister; they are like family to you.

Your personalities match perfectly and you get along very well. You can tell them anything and they can tell you anything. Your souls are in sync.

Similar to brother from another mother or sister from another mister but no relatedness is implied.

1) Craig and Danielle are my soul siblings.
2) You see that guy over there, he is my soul sibling.
