Biffle 

The bond between two people that are normally of the opposite sex. Not to be confused with friends with benefits. The people people may seem like more than friends, but to them, they couldn't ask for more. They love each other more than most friends do, and they would do anything for each other. They hold a special place in each others heart. Most biffles later on end up dating, but they still hold that biffle status.

Ashley and Brandyn are biffles.

Johnny: "Hey look at those two. They must be having sex."
Craig: "Nah, they're just biffles, dude."

biffle 

An idiotic word which shows how the acronym 'BFFL' would be written if it became a proper term, god forbid. It means 'best friends for life', although in most cases this is generally a lie as you often lose contact with friends, especially if they were made when you were young.

Biffles would be the plural.

"You're my biffle... (may continue with other ramblings; but it's optional)"
