The American science communicator Emily Calandrelli (also known as The Space Gal, @TheSpaceGal on Twitter) published a very funny video on her Twitter account, which can be titled “Please use crewed, not manned”.
To explain her cause, Calandrelli used the popular “Joey, the famous ‘Friends’ character being taught French” meme, where Phoebe hopelessly tries to teach Joey French.
Calandrelli also posted that video on Facebook saying “a friendly reminder”.
NASA style guide: “Please use crewed”

The current NASA style guide recommends using the word “crewed” instead of “manned”.
Gender-Specific Language (e.g., Manned Space Program vs. Human Space Program)
“In general, all references to the space program should be non-gender-specific (e.g., human, piloted, unpiloted, robotic, as opposed to manned or unmanned). The exception to the rule is when referring to the Manned Spaceflight Center (also known as the Manned Spacecraft Center), the predecessor of Johnson Space Center in Houston, or to any other historical program name or official title that included “manned” (e.g., Associate Administrator for Manned Spaceflight).”
