I'm guessing it's a paragraph of text that you recite every morning at the daily stand-up.

"I did X yesterday, starting Y today, no blockers."

Stand-ups are such a waste of time.

Only if you talk about things other than blockers (and say hi to your teammates). Standup isn't a status update, etc.

In the agile/scrum world people often do a daily "standup" meeting where you go over what you did yesterday and plan on doing today.

Many of the teams I've worked with recently have moved to doing this async with a "standup" message in slack etc.
