BBF stands for Bed Baggy Fuck, or Fucking. This is the act of putting a plethora of lubrication in a sandwich zip-loc baggy. After you do this, make sure it spreads, then go to your bed and life up your mattress slightly. Place the back 75% of the bag under the matress so the open end is sticking out. open baggy, insert erction, and proceed to fucking.
