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."

Musty Finish

Derived from the skill of hitting a musty flick (from Rocket League), Someone involved in sexual intercourse gets very close to finishing, and right as they are about to blow a load, they hit a backflip, stick it back in, and bust inside. Basically Backflipping and busting.

I just hit a crazy Musty Finish!
She asked for the Musty Finish

I want him to Musty finish inside of me.

Musty briefcase

Having sex with a girl and realizing she has mold growing on her vagina.

I was doing this girl this morning and I looked down and seen she had a musty briefcase.
