Polish Roadblock 

When someone, usually in an SUV, drives in the passing lane directly alongside somebody else, thus keeping faster traffic from getting by.

I'd have gotten here quicker if there weren't so many Polish roadblocks on the interstate.

Roadblocked 

When an typically grassroots political party or movement gets killed off because the pseudo-democratic powers at be don't like it as it interferes with their agenda. In doing so the illusion of democracy is thought to be maintained as it doesn't appear too blatant and the movement ends up disappearing leaving people with no alternative by the time an election comes. Thus the cycle never ends yet the government will claim democracy works and gives everybody a choice.

Usual methods of roadblocking include but are not limited to: getting hijacked or bribed, not given any media time , paid or being classed as a terrorist organization.

Guy 1: Since when is the EDL a terrorist organization?

Guy 2: Since they got roadblocked.

Minnesota Roadblock 

For any cars travelling on the interstate in the fast lane that go the same speed as the car in the slow lane. This essentially blocks all cars from passing them.

Last night I was travelling home from work on I-94 when I got stuck behind a Minnesota roadblock.

Asian Roadblock 

The Asian Roadblock is when a group of Asian students spread out over a sidewalk or other heavily trafficked walking route and decide to walk at 0.2 feet per hour. This phenomenon has been noticed at all universities across North America; experts speculate that it is a scheme set up by Chinese agents in order to stifle the progress of Western higher education.

Professor: "Why are you late for class?"
You: "Sorry, I hit an Asian Roadblock, I was stuck behind them for 30 mins."

A Mexican-roadblock occurs on a two or more lane road where 2 (or more) cars are traveling next to eachother at the same speed (usually under the speed limit), not allowing the following traffic to pass.
