DDD very clearly stands for Double-D Deprivation. This is an extremely common, and quite serious condition, in which one has not seen, let alone come into contact with, a large set of breasts in a very long time.

Possible known side effects include twitching of the eyes, seizures and prolonged periods of shameful masturbation.
John: "What's wrong with Sam? His left eye was twitching during science class and then he went into convulsions."

George: "Word on the street is that he has DDD. It's pretty serious."

Designated Drunk Driver. A DDD is the person who is the least drunk and serves as an emergency DD. While it is safer to call a sober individual it is common practice to use a DDD
Person 1- “Hey man I couldn’t find a DD. How many drinks have you had?”
Person 2 - “I think I’ve had 10 beers and 3 shots”
Person 1 - “ ok I’ll be the DDD then, I only had 9 beers”

Designated Drunk Driver- A person who refrains from drinking while in a bar with a group of freinds, so that when he staggers out to his car (acting like he's completely hammered), that he parked right in front of the bar, he will draw the attention of any cops that may have their eye on the place. While he's doing this his drunk friends will be able to get in their cars (parked further from the bar) and not get pulled over.
Tom volunteered to be the DDD tonight, so if your planning driving tonight don't leave 'till after 1:30, that's when he'll be doing his part.
