Little Sister

You're probably here because you got into a fight with your little sister and so you searched this up to see what Urban Dictionary has to say for you. Well let's see...

A human being who has been tormenting you ever since it has appeared on this earth. Someone who has been annoying the crap out of you and getting you in trouble for no reason whatsoever. Someone who pretends to be a saint but in fact is quite the opposite. Nevertheless you still care about them even if you keep on telling yourself just how badly you want to slap that brat in the face, but without getting in any form of trouble though.

Person 1:

*Wants to use perfume*
*Sees that it's empty*
"Lili, what did you do with my perfume?!"
*Walks over to her bedroom*
*Notices little sister trying to hide something in a rush*
"What is that?!"
Person 2:

"I'm making a bubblegum scented air freshener..."
Person 1:
*Notices a cotton pad literally dripping with perfume with a small flower cellotaped to it*

"Are you insane?! You wasted all of my perfume!"
*Slaps her, just a little bit*
Person 2:
*Starts crying like as if she hit her so hard*
"Mummy!"

See this is what I'm talking about. They constantly annoy you until you can't hold yourself together any longer.
