The new terminology for
friends.
"Best
friends for Life"
Either used to mock shortened
computer lingo as in "omfg we are sooo bffls!" or mistakingly said when referring to a friend, can slip out in coversation by accident like LOLs sometimes do.
Jesse: Why are you hanging out with Karen? I thought you hated that bitch?
Mary: Oh god no we bonded in the ladies room the other
day and are totally bffls!
"Omg Stacey and
Lindsey are like joined at the hip .. they are like over the top bffls!"
