BFFAT 

BFFAT stands for "Best friends forever, always together." Usually said by someone named Jenna or Chelsea. This term is mostly used when someone is trying to end a friendship. May also be confused as standing for "boyfriend fat"

Oh my god Chelsea! You said we were BFFAT's! Why are you avoiding me?!?

BTFATH

Buy The Fucking All Time High

Used to describe the actions of investors who go long on stocks (buy) when stock markets hit new alltime highs. Usually this is seen as the worst possible time to invest, because markets have tendency to crash shortly after new highs.

BFFDTS

BFFDTS.

Best Friends Forever... DURING THE SEASON.

When 2 people, be it guy or gal. Swear they are

BFF, during a sport's season, lets use soccer for instance.
They upload pics, post statuses, become relatives on facebook and hang out . Then season's over, they hand in their uniforms, and hand in all that love you forever crap with it. And suddenly one person is " awfully busy" and can no longer chill. That person is usually the mini hitler, to the friends of the person who actually believed they would be BFF.

Dude 1 : Yo since when does Vivianne hang out with that

white-ass girl Nicky?

Dude 2 : Yo Vivianne, is brazilian you know she's only dealing with that hannah montana shit till seasons over.

Dude 1 : a case of BFFDTS?

Dude 2 : yes, a mild one tho, they never got married on facebook.
