A min-maxer is someone who tries to maximize the minimal amount of efforts to make in daily life.
It often happens in crowded cities, where people don't hesitate to
cut you off, so that they make the least amount of steps to go where they have to. In the process, they pretend they
don't see you, even though you had to stop at 1/12th inch of them, right before bumping into them.
Parisians excel at this.
