Coarse is believed to have come from course, which came from Latin cursus, "a running race" or "course", from curs- past participle stem of currere, "to run".

It developed a sense of "rude" in about 1510 and included the meaning of "obscene" in about 1711.

Apparently a misspelling of concourse because it can not be found in a dictionary; however, some automobile companies are using the term for specific car models.

You are advised to use concourse if you are referring to an assemblage; a gathering, a large open space for accommodating crowds, as in a railroad station, a park, or an airport; an act or instance of running or coming together; a confluence; such as, a concourse of events, etc.
