Teachers' Day is a special occasion for students to express affection and appreciation for teachers, who have to deal with their underlings' nonsense the rest of the school year.

To commemorate the occasion, Temasek Polytechnic uploaded a video on their Facebook page on Aug. 28, featuring some lecturers and their students who find their roles being reversed.

Students teaching lecturers

The premise? Students teaching lecturers some millennial slang.

Needless to say, it went down hilariously.

If you're conserving data and can't watch the video, here's what went down.

So, the students presented a few millennial terms like "on fleek", "lit", "pops" and "low-key."

Of course, it gets taken at face value at first by the lecturers:

Millennial slang builds relations

But being a teacher, eventually, they started questioning and even picking on the grammar of slang usage.

And of course, heartfelt gratitude was expressed for the hardworking teachers:

Awww.

To all teachers and educators, here's to a very Happy Teachers' Day.

To students, don't forget your homework, though.
