A stupid phrase Cj uses to pick on Dajia, and Dajia is too dumb to know he's being messed with.

Cj yells 'La momma' at Dajia during lunch and Dajia just stares at him.

Dajia texts Cj 'What does La momma mean?' and Cj says 'I don't know, I just say it to make you mad.'

Cj uses 'La momma' in a group chat and Dajia asks why everyone is laughing.
