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.

New York Traffic Jam

When the female is having anal sex in the cowgirl position. She commences flatulence into gradual deification, as the man is about to climax.

Brandon "Dude! She totally did the New York Traffic Jam on me last night. I still can't get rid of the stain."

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.

LA traffic stop 

Slamming on your brakes for a random fucking merge, and going from 70mph to 0mph in t-minus 5 seconds on a LA freeway.

Person not familiar with merge spots:
OMFG stop stop stop its an LA traffic stop. Holy Sh!t, (crash)

LA driver: He didn't factor in the random fucking merge, and in a LA traffic stop, he rear-ended that hybrid.
