College professors try (and fail) to guess millennial slang

College professors love to make their students read their work, understand their opinion, and listen to them — but they often don’t speak to millennials.

USA Today’s Collin Brennan interviewed several professors from Christopher Newport University to see if they could guess what some popular millennial terms like “on fleek,” “lit,” and “Netflix and chill” meant.

“On fleek” means something is flawless or close to perfect, but only two of the professors, including communications professor Jennifer Billinson, who teaches a course related to how millennials talk online, had any idea.

“It actually comes from a Vine,” Billinson informed. “A lot of people think it originated on YouTube but it actually comes from a Vine.”
