JoJo Moment means in slang: The meaning of a “JoJo Moment”, is very similar to that of the term “Bruh Moment”. But instead of saying “Bruh”, we gasp and shout “N-Nani”, M-Masaka “YaYaroouuuu”, or other similar words. JoJo Moments can also be used when somebody is saying these words, and you respond by saying “HeSheIt’s having a JoJo Moment ..”. (in Slang Dictionary, added by Fabio Álvarez)
