To let them know how well things are going, you text them a simple message: “dwu”. You smile wryly and start picturing what else the night has in store.

This post unpacks the meaning and origin of this expression.

Meaning

DWU is an acronym meaning “Don’t Wait Up”. If you are trying to tell someone to move on, go on, or not to worry or wait on you, DWU is the perfect acronym. It is a straightforward way to say that you likely going to be late or not make it at all.

It can also mean not to worry about something or someone.

This term became popular in the early 2000s and was used to shorten the phrase “don’t wait up” in their texts and on social media. It has since evolved to take on a broader definition to not wait on someone forever or allude that one is out hooking up or partying.

Origin DWU

“Wait up” is an idiom dating back to the late 1700s or early 1800s appearing in a record of the proceedings of the British House of Lords. It was used in reference of a man telling his servants “not to wait up for him,” because he “had a key to let himself in by.” Since, it has become a common phrase literally meaning not to go to bed at night because you are expecting someone to arrive. “Don’t wait up” instructs the message recipient to go ahead and move on with their plans as usual and not make special accommodations for the sender.

In addition to the phrase being used in common text exchanges, it is the title of several songs including one by Shakira (2021), by Robert DeLong (2015), by Twang (2007), and Colin Hay (2001). It is also the title of a British sitcom that aired between 1983 and 1990, and the title of American punk band Bane’s 2014 album.
