MPF
otherwise known as a Multiple Posting Frenzy. The act of leaving many posts in a row on a friend's page. Usually a response to insomnia, caffeine, alcohol, stimulants or a genuine desire to annoy others. What these posts lack in quality they make up for in sheer volume.

The act of posting on a person's wall until your posts are the only posts visible on their wall.

The facebook version of drunk-dialing.
Tiffany was shocked to find that she had 28 notifications on facebook from the night before, all from her crazy friend Kate. She just chalked it up to one of Kate's caffeine-induced 2 am MPF's.

Last night I got drunk and had an MPF all over my ex boyfriend's page.
