DDD
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.
