It can be used on its own, but it is typically used as a response to counteract "No big deal" or nbd.

Also for emphasis: pbfd = "Pretty big fucking deal."

1. Person A: "I just saw Joseph Gordon-Levitt walking out of Starbucks, nbd."

Person B: "Uhh... pbfd."

PBD 

PBD, otherwise known as post beat-off depression is the state of mind that males will pass into after masturbating. The male may wonder why he did such a thing, think it was gross, and then cancel that 800mb porn download that had been going all day. This is commonly followed by DAR.

"fap fap fap ughhhhhhh"
"ewww that was gross...."
"I'm gonna take a nap to get rid of this PBD."

Ugh, I hate my life so much! I am totally suffering from PBD.
