BFB
Breathing for Batman. In anticipation of the summer blockbuster The Dark Knight, many fanboys have come to use this as a way of expressing their 24/7 love for the film. This can also be used rhetorically or sarcastically against aforementioned fanboys.
From now til July 17, I'm just BFB all the way.

No way Ryan is gonna want to go out Friday. He's gone gay for the week, big nipple suit lovin' BFB.
