A high school teacher's attempt to connect with students has turned into an internet sensation, thanks to a post online by her adult child.

Her child, who posts as u/signal-replacement85 on Reddit, told Newsweek that the whiteboard list of "banned" Gen Z slang words their Texas-based mom had created with their co-lab U.S. History teacher was intended as a lighthearted classroom joke.

The post, shared to Reddit on October 21, showcases words like "bruh," "bro," "lowkey," "finna," "rizz," and "sigma" -- all of which are commonly used by today's teens.

The Reddit user's mother, a veteran educator with 17 years of experience, had watched her co-lab teacher write the list with a smile aimed at eliciting giggles from students rather than stern enforcement.

"She's a high school sophomore teacher just trying to have fun with her students," the Reddit user told Newsweek. "Some people in the comments were thinking she was serious, but it was all a nice little joke in her classes."

The teacher, who has two adult children, has witnessed the evolution of student slang firsthand.

"She writes these words on the board with a smile on her face, rolling her eyes as her students laugh," the Redditor added.

Since going viral, the post has sparked an array of responses, some from other teachers sharing their amusing classroom anecdotes.

"High school teacher here, one who had to teach his AP Chemistry students about sigma bonding today," one commenter said.

"As a high school physics teacher, this week and last week we learned about net force equations which is written as...Sigma F...The amount of chuckles....Allow me to sigh with you," another Redditor wrote.

"She wrote it as a mother who heard her own two kids grow up in the 'YOLO,' 'swag,' and 'lit' eras and remembers laughing with us, and it is driving her nuts," the Reddit user said.

Now in their twenties, they and their sibling shared a hearty laugh at the post's reception, realizing it had struck a universal chord.

The teachers have since shown their students the viral post, which has been upvoted more than 55,000 times. The Reddit user says their mother's students were left in stitches by the many comments and their teacher's sudden viral fame.
