Pack Jam 

When an ass load of people get jammed together at a club and everyone is just grinding on everyone.

Or when you get jammed in between two people like when pac-man gets trapped by two ghost.

"Look at all the fine bitches in that pack jam!"

Jam packed dream 

A dream that was absolutely FULL with different events that happened. A jam packed dream will probably not leave your mind for a while and there’s a good chance you’ll remember it in the future!

Person 1: Hey did you dream last night?
Person 2: Bro you bet I did. I had such a jam packed dream it was crazy!
