Term became popular through a commercial gay porn site with the same name that featured almost exclusively well-hung Straight- or Bi-sexual guys, most of them with an Ethnic background, who had rough sex with mostly smaller, white or Hispanic gay boys. The immense popularity of that aforementioned website led to the fact that everyone using the term "Machofucker" in, for example, private contact ads or profile pages on gay contact sites, could be assured that the reader would make the right association what the writer meant by using this term.
