'Young, Dumb, and Broke' are not usually qualities that you would idealise, but Khalid has written a song that revels in the nostalgia of youth gone-by. Or, a song that celebrates carefree fun in the face of impending adulthood.
It just depends on your perspective.
In the video, Khalid dances a charming and awkward dance throughout the halls of the high school as kids frolic, eat pizza, play with water guns, and never do any work at all.
To be fair, it seems like the video is set at the very end of a school year.
The video features shots of various students and their associated "Most likely to" yearbook awards, including the hilarious "Most likely to not give a fuck".
The video also has cameo appearances by Dennis Haskins, Wayne Brady, and Rachael Leigh Cook.
