Rapper Lil JoJo (Joseph Coleman, 18) was murdered in the name of gang violence in Chicago, IL on September 4, 2012. He was shot and killed while riding a bike in Southside Chicago's Englewood. People often use the terms “on Lil JoJo” or “on JoJo bike” to swear by the name of kids who have wrongfully died to gang violence. It's spoken similarly to "on God."
A) "It's 2022 and these kids are still dying in the streets. We need to be able to protect our children – this is out of hand."
B) "On Jojo bike bro. It's heart-breaking."

Get the jojomug. A person that will always seek attention, no matter what they will have to do to get it. They will be rude, annoying, and downright childish all too often. Not a pleasant person to have around.
MAN: Oh man, I just saw JoJo walking down the street.
WOMAN: Yeah, and I think all of China heard him screaming.
