2. What does HU stand for?

Heads up

HU stands for "Heads up," which is another way to say "Watch out." It is typically used online, in emails, and in text messages as a warning.

The origins of "Heads up" date back to the 19th century, eventually becoming a popular way to notify people that something is about to happen. It is often used when playing sports to warn people to watch out for an errant football pass, basketball shot, or baseball throw.

While the "Heads up" saying has been around for centuries, the "HU" acronym did not become common until digital communication became more prevalent (1990s and 2000s). In text messages and online, the acronym is used as a quick way to warn somebody, and in email communication, it is often used to warn co-workers of a change in the business plan.
