In all fairness to these professors, I bet most people over the age of 30 wouldn’t know these words.

This is pretty funny.

ABC News in Los Angeles has more.

Lehigh University in Pennsylvania challenged some of its instructors to step away from more familiar subjects like engineering, finance, economics, and yes, even communication, to see if they understood terms likely to be used by their students.

One professor speculated that “FOMO” could be secret code used to let others know their parents are gone — “Father’s Out, Mother’s Out.” In reality, the acronym stands for “Fear Of Missing Out.”

“On fleek,” the quality of being perfectly executed or on point, proved especially challenging to many of the instructors.

“Can’t even begin to tell you, but poor Fleek, because everybody’s jumping on him,” Georgette Chapman Philips, dean of the College of Business and Economics, remarked.
