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!"
