This term refers to the group of people that think it’s cool to vape in high school bathrooms. Always skip classes and when they do show up they are high. Are you type of person to scream, “where’s my juul?” after miss placing it.
“Why is there a group of people vaping outside the school?”
“Those are groms, don’t pay attention to them.”
