LDD

Acronym for Least Drunk Driver. Usually delegated after a Designated Driver has been established and that driver gets smashed more than anyone there.

It's always good to have at least one LDD established.

LDD

LDD, or Lego Digital Designer is a CAD-like program for use on both macs and PCs. You can create your own lego models on it and upload them to the Lego website, where you and other people can buy them. The most recent patch was this April, contains several new parts, though there are tons still missing. In addition, the parts in LDD may have a different price on the website.

LDD is a great tool for beggining engineers and pros alike.

Also, Legos is not the correct plural, Lego is.

LDD

LDD (Long Donkey Dong) is a term used by the vampire traders in the Dr. Bob School of Forex Trading. It is a type of pattern seen in forex and stock trading charts. It is easily identified by a string of short candles staying inside the bollinger bands on a candlestick chart. It is an indication of a lack of direction and consolidation in a forex pair or stock, and is a very risky time to trade, since a channel breakout tends to lack much momentum in either direction and could turn back around and return to the channel quickly. The name of this pattern is derived from the similarity in appearance of this type of channel to the extended male member of a donkey.
