People, usually girls, who do EVERYTHING together! Whether it be boring family stuff or shopping. Someone who is always there no matter what, even if you are being a bitch. Someone who knows when your lying and why without even asking. Someone who tackles you for the last gummy worm, or will forgive five minutes after having a fight. Someone who truly loves you for you and would die for you. Hoes before bros.
"Did you see Olivia and Maddie, they're hanging out AGAIN!"
"That's because they're true best friends"
