The Keith Lee Effect is when a struggling restaurant soars in profits and popularity seemly overnight after a review of the restaurants food is posted on Tik Tok by food reviewer, Keith Lee.
Person 1: âWow! Look how long that line is! I donât remember that place ever being that popular before.â
Person 2: âThatâs the Keith Lee Effect. He posted a review of the place a few days ago on Tik Tok and itâs been super busy ever since.â
