A fork of Rural Dictionary
A smart, beautiful sibling who always has good advice for her brothers, who are always acting like buffoons.
Brother: Oh no! I have nothing good to wear on my date with the school slut!
Sister: I think you should dump her, you might get an STD. But if you insist on dating her, you should wear your black slacks and this white button up shirt.
Brother: Thanks Sis! You know what, you're right! I will dump her, and I'll ask the new girl out instead! Thanks a bunch!
Sister: You're welcome.
