One of those texty abbreviations for "best friend forever," which became one of those corny, douchey, CW-ish, The Hillsy things said by white females and the reporters on 7:30 entertainment shows. It's right up there with OMG, OMFG, g2g and ttyl on the gayness scale.
Extra: Lindsay Lohan and her BFFs Britney and Paris were seen bar hopping along Sunset.
Me: Can't remember the last time I gave a sh*t!

BFF best known as Best Friends Forever, is something used to describe one or more than one close friend that you have. They will always be there for you no matter what or what you have done. They are the ones you can trust with all your heart and the ones who are going to support you, and tell you if your doing things the right way or the wrong way. They will always be loyal to you, if you ask them " How do i look today" they will always tell you the truth whether it hurts or not, if they did something wrong they will tell you because they trust you, and as they support you you have to support them too, because they are not being loyal and nice to you just so you turn your back on them and talk shit about them. Treat your best friend like a brother, sister, girlfriend, boyfriend etc. Be nice to them, because there is nothing more beautiful than having a best friend who will always be for you whether things are good or bad. So always remember to love your best friend as a brother or a sister, and to always be loyal to them.
"Hey BFF, how do i look today"
"Umm, to be honest BFF. you look okay, i think you should change the skirt to jeans, it'll look better"
"Ugh, you're so annoying and picky but thank you, and you might wanna change your shirt it doesn't match your look"
*Both laugh*

Your "Best Friend Forever". Someone you know you can trust. A sibling from another parent. The one friend you hang out with the most. Someone who will laugh when you laugh, cry when you cry, and smile when you smile. They will stand up for you, and they will listen when you blab on and on about all of life's problems.
I can tell my "BFF" anything in the world, and they will listen.
