When you're walking along and unable to pass the people in front of you who are walking slowly, occupying the entire width of the walking space, and oblivious to the fact that you want to pass, usually because they are inconsiderate morons engaged in mindless discussion.
Coming back from lunch today I was walk blocked by these two fagtards talking about football.

While driving, being unable to make a turn at an intersection due to pedestrians getting a walk signal and walking across the crosswalk.
Everyone wanted to turn left but only one car made it through the light because we all got walk-blocked
