An alternative to "gentlemen"

[Lyle1]

If memory serves, "dude" originated as a "non-honour" informally but definitively assigned by late 19th--20th century American Westerners (ranchers and "cowboys") to newcomer poseurs or at best, wannabes entering their world.

The "Dude" was recognized by new clothing and inability to "properly" ride, rope, shoot...endure...and had not earned the right to be a member of their society. "Tenderfoot" also applied, though may have been slightly different in definition.

Ergo, a query; why do some X Marks forum people wish to identify themselves therewith?
