when a high school kid's parents are gone for the day but will return at night, he will have a day jam. It is a party during the day. Usually people will smoke pot or drink.

expression to indicate in a more polite fashion to go fuck themselves. It is best used with close friends or family to show your displeasure with them without cursing

When you're stuck in traffic listening to the radio and you notice the car next to you listening to the same station. You both roll down your windows and start jamming.
I rolled up next to a guy in traffic today listening to the same song on the radio, so I rolled down the window and we started traffic jamming.

Cindy at work is so hot she gave me a raging hard on. In order for anyone else not to see it I gave it a knob jam.
