Short for defragmentation. To understand what defragmentation means, you must first understand what fragmentation is. Fragmentation is when entire files are broken down into many pieces and spread across the hard drive. This can also happen regarding free space on the hard drive. Now, defragmentation is the action of collecting the various “fragments” of files and grouping them back together.
My PC was running slow, so I used Diskeeper defrag to speed it back up.

1. To rearrange data on a disk so that it is stored seqentially rather than randomly, thus decreasing total access times. Fairly useless on new, fast drives.

2. Antonym of frag. Ie, to bring someone back to life.
1. Dirko: My 486 is running like a bag of shit.
Atticus: Defrag the dunga!

2. Game consol: Dirko was fragged by Poonani
Dirko: Damn, I need to be defragged. This definition is so stupid.

My laptop's been choking up pretty badly recently... speed-wise, that is. I'm going to see if I need a defrag or something.

1. To half-smoke a weak 100mm cigarette, in order to let the other half relax and collect flavour. Stems from half-smoking a fag, expecting your hard-drive to defragment faster, then putting it out to smoke it the rest when you come back.

2. To relax, chill, mellow out.
1. I'm defragging that Du Maurier. Don't touch it.

2. Ah, sit down and defrag. You look awful.
