Any device such as a cell phone, iPod, or gps that causes a person to look down while driving or walking. The opposite of a heads up display.
Chuck! Quit looking at that heads down display and look me in the eye!

Like the universally despised PDA (Public Display of Affection) the PDE, or Public Display of Engineering involves two or more engineers engaged in a deeply technical, often hotly and loudly debated, all-encompasing discussion that while titillating and intensely enjoyable for those involved, is utterly cringe-worthy to behold.
Ugh, the Public Display of Engineering going on behind us is unbearable... Get a conference room, you two!

plural noun: Also known as PDP, Public Displays of Perfection can ecompass a variety of acts put on by people to show others how superior they are to those around them. PDP range from "My Child Is An Honor Student At Kiss-My-Ass-You-Know-I'm-Better-Than-You PreSchool" bumper stickers placed on outlandishly-expensive, over-sized gas-guzzling SUVs, to trophy wives with ridiculously giant breast implants, not-of-this-world-colored blond hair, thousand-dollar extensions, spray tans, and stick-figure-thin arms dripping with jewelry, the value of which equals the gross national product of some nations, strapped to the sides of men who they never would look twice at except for the fact that they own three homes, a yacht, and several race horses.

Public Displays of Perfection can also be as simple as a woman primping herself in her rearview mirror, tossing her hair around, and purposefully holding up traffic so everyone around her can take in how absolutely gorgeous both she, her vehicle, and her yappy little lap dog are.

Men are known to succumb to PDP even without trophy wives. This usually happens in places such as gyms or other venues where groups of men gather and find themselves shamelessly flexing and posing as though they are about to be crowned the next Mr. Universe.

Men seem to use expensive sports cars for their Public Displays of Perfection, not realizing that women could give a fuck what they drive and actually find these PDP quite juvenile.
Did you see that guy with the Corvette and the chick with the boob job? What a couple sad Public Displays of Perfection!

1. Your brain melts.
2. A black hole suddenly appears next to you, sucking everything into it.
3. Death to all those around that person.
4. The president is assassanated.
5. Blindness.

To those who thought there couldn't be worse than that couple slobbering noisily all over each other centimetres from your own face at rush hour on the tube (Public Displays of Affection) - think again.

There's always Pathetic Displays of Affection. These usually occur when one or both parties is irretrievably inebriated. Sometimes followed by convenient memory loss the morning after the night before and/or heavy regret and shame felt by one or both parties.

Almost without fail intoxication-related, Pathetic Displays of Affection can be physical or virtual - in which case, thanks to the miracle of modern technology, they can take the various but inevitably excruciating forms of drunken dialling, texting or even, more permanently so, emailing and instant messaging.
Pedro, spare us all the PDA (Pathetic Displays of Affection) and the ensuing wingeing phone call to me about how mortified you are. There is no world in which it's a good idea to tell this Madeleine girl you just met at the bar that you want to marry her and impregnate her shortly afterwards. Even if she IS a hot blonde blue-eyed Swede.

Apple's latest Macbook Pro that is "revolutionary." It's newest features include the crisp Retina Display that beholds a resolution of 2880 x 1880, a quad core processor standard in every model, and a standard of 8 GB of RAM. Great for the power user and not worth it for people who want to look at cat photos and their pr0nz.
1. Person 1 "I just bought my new Macbook Pro with Retina Display so I can edit faster with Final Cut Pro x, Aperture, and Logic."
Person 2 "Nice."
2. Person 3 "I love looking at pr0nz and cat photos, so I bought a $2000 computer with a "quad core cpu and 8 gb ram" lol, like whatever the hell that's supposed to mean. Anyways, I hear it has a nice display"
Person 4 "You could do that with the regular Macbook Pro just as fine cause you wouldn't notice the screen difference being such a noob, and that's only $1200"
Person 3 "ur just j3l0us"
