Jam tin

A type of improvised grenade-like bomb used mainly in the first world war. Soldiers would use the empty tins from their ration of jam and fill it with explosives and shrapnel. Improvised jam tins often resemble the 'Double Cylinder Bomb' that was in use at the same time.

"I managed to kill two guys in trenches today using a couple of jam tins"
or
"Shit, a jam tin went off next to me and now I've got shrapnel stuck in my leg"

traffic jamming

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.
