Jum is a word my sisters and I made up and we basically use it as a filler when we don't know what word to use...we use it so often our friends, parents, and even some teachers have taken to using the term. Here are some ways to use it:
1. (n) stuff, crap, junk, things etc.(usually with a negative connotation)
2. (adj) Very, extremely. often used in the phrase "jum good"
3. basically a filler word..may be used in places of "hell" or "heck."
1. You should probably get your JUM out of my locker, I can't fit my nunchucks.
There was some sticky JUM at the bottom of the cup.

2. That orange juice was JUM good!Extra pulpy!

3.What the JUM was that?
Get the JUM out of my way.
I don't give a JUM what you think.
