A reader has encouraged Etiquetteer to speak out on the issue of men sprawling beyond the limits of their seats on public transporation, which has been given the Vulgar Appellation of "man-spreading." Indeed, this issue has become such a Menace to Public Decency that the MTA has inaugurated a campaign to curb it. A gentleman does not take up someone else's space. And that should be quite sufficient.
Really, Etiquetteer compares this Ostentatious Behavior to blaring one's car radio (or do we have to call it "sound system" now?) outside the limits of one's car, or revving one's motor to call attention.
In short, Etiquetteer considers Excessive Sprawl advertising one's shortcomings.
