"John" was so far behind at work that he decided to take his BlackBerry into the bathroom with him to catch up on email. He was so proficient at BBWD (BlackBerry While Driving) that he decided to make the most of his hours at work and proceeded to BBWP.
This can be used when you're feeling a guy or you deadass down for him but he playing. So you can save him in your phone as this or...when talking about him you could say "He's my BBHP".
