ONM syndrome 

Person who is more confortable in the world he has created in his mind THAN IN THE REAL world. Sometimes, it can be that at one moment he/she disconects for a few minuts and gets to this imaginary world.

A student is in a class and suddenly he remains in motionless, and he starts making grins. That would be a slight case of ONM syndrome

ONM(musty)

Similar to the ONJ(jee) one however Musty is known as the "mystical one" the title going against Jee's "magical one". Both are from the same lore/universe but ONM has a deeper meaning. Unlike ONG you're swearing on the mystical one himself. But you're also swearing on his WD40. Musty uses WD40 as a form of moisturizer. This is usually followed with the gif "ONM(musty)" gif which consists of WD40.

Person A: "Bro icl, you could be lyin so hard rn."

Person B "Trust, ONM(musty) im not lying."
