Hallway Traffic Jam 

When in a hallway, often in High School or Junior High, when at the end of the day or on the way to lunch when there is a tight jam in the hallway as everyone attempts to get to their locker, the cafeteria, etc.

"Dude! During the Hallway Traffic Jam today after the bell rang I think I felt some girl's boob!"

foot-traffic jam 

The traffic jam caused by people leaving public events all at once. The roads are normally closed, and it is difficult to move.

Lisa: Let's leave now that the fireworks are over.
Shaun: Let's wait half an hour, the roads are packed... There's a foot-traffic jam.

Portuguese Traffic Jam

Having sex in a sub-compact automobile on a hot summer day without an A/C with an older woman who looks stunning from the backside and hideously old from the front.

After the Indian cook was finished making a seafood dish, the kitchen smelled funkier than a Portuguese traffic jam.

unidentified traffic jam 

When you're driving on the expressway and all of a sudden you come to a screetching halt because of traffic congestion that appears to come out of nowhere (no accident, no bottlenecking, no construction). So you then cruise at about 5 mph for a short while wondering what the hell the deal is. Then all of a sudden, the road clears up and you find yourself cruising back again at a normal speed.

I was drivin' on the Parkway goin' 75 mph then found myself slammin' on the brakes because of some friggin' unidentified traffic jam. A minute later the roadway cleared as if nothing happened.
