J.M. 

He is the greatest person you'll ever meet. Although he may be a little chubby, he is the kindest and sweetest person ever. He loves playing basketball, watching the hit TV show Friends, and is a huge fan of post malone. He's the type of person you'd love to work with, no matter the task. If you meet such a person with the same initials, try to be friends with them.

Audrey:J.M. is the star player of the school basketball varsity.
Sarah: Oh! what a chad!

J&M Stage 

When your confused but walk to the bus together (hugging) and other such actions, but dont want to be considered talking. Also, the word friend is used to hide what the 2 people really mean.

John: Hey Margarett, lets make it seem like we are just "friends" as the J&M Stage
Margarett: Ok cool!
