Two people who are better than best friends. They are Best Friends For Freaking Life. They share almost everything in common and basically have the same thought process. Often times they are mistaken as sisters. These two people talk about anything and everything, the two cannot hide anything from one another because the other one has a Best Friend Sense.
You're my bff!

You're my bffl!
We are better than best friends we're Biffles!
Kaitlyn says to Angela, "I love you, you're my Biffle forever!"

Angela responds, "OMG, you're my Biffle forever!!"
Both agree and say, "I love you Biffle!"
