If there's one thing no pre-teen can resist, it's a colorful party invite.

When her younger sister continued to get bullied by a group of girls (Elke, Grace, Ashley), this big sis stepped up and crafted a colorful invitation to a "stop being jerks" party.

When: Right now
Where: Everywhere
What to bring: Bring your nasty attitude and throw it right in the trash can
Why: You guessed it folks, you're being jerks
