DD

1. What is a DD when drinking alcohol?

Designated driver

A "DD" is a "designated driver," which is a person who must stay sober to provide a safe drive home for their companions (usually from a bar or nightclub). The DD is typically the most responsible person in the group of friends, but the group may also choose them randomly or take turns with their friends.

People often use DD in messages, whether online or in texts. For example, your friend may text you and others in a group thread asking, "Who wants to be the DD for our trip downtown tomorrow?"

Origin of DD

It is unclear who coined the "DD" acronym, but it gained popularity in the late 1990s and early 2000s. Also, it comes from a PSA initiative in the 1980s meant to reduce the number of car crashes caused by intoxicated drivers by encouraging people to designate a sober driver for the group.

Example

2. What does DD mean when discussing stocks?

Due diligence

When you're discussing stocks or other investments, DD stands for "due diligence." Financial advisors, finance forum posters, and investment-related websites often tell investors to perform their own DD before buying in to any company.

What, exactly, DD involves is up for debate (see the Reddit example pictured below). However, doing your due diligence on a company and its stock typically includes:

  • Investigating the company's balance sheet, cash flow, and management
  • Comparing the company with its competitors
  • Assessing the company's strengths and weaknesses
  • Considering industry and worldwide trends that may affect the company
  • Examining the company's short- and long-term growth

Only after you've completed all these tasks (and potentially, a few others) have you performed your due diligence.
