Does “Lock shat hoo-la ma sho gong um hom tak ti-wak yet gee sam see baa gow!!” mean anything? The book The Chinese Typewriter by Thomas Mullaney has the following Cartoon from the San Francisco Examiner (1900)



and explanation:


  The first mass-produced Chinese typewriter was a figment of popular imagination. It was first sighted in January 1900, when the San Francisco Examiner spread word of a strange new contraption housed in the city’s Chinatown neighborhood, in the back room of a newspaper office on Dupont Street. The machine boasted a twelve-foot keyboard complete with 5,000 keys. “Two rooms knocked into one apartment afford shelter for this remarkable contrivance,” the author explained, describing a machine so large that the “typist” was something akin to a general commanding forces over a vast terrain (figure 1.1). The piece was accompanied by a cartoon in which the caricatured inventor sat atop a stool and shouted Cantonese-esque gibberish at “four muscular key-thumpers through a large tin megaphone.” Lock shat hoo-la ma sho gong um hom tak ti-wak yet gee sam see baa gow!!


I realize he calls it gibberish but does Lock shat hoo-la ma sho gong um hom tak ti-wak yet gee sam see baa gow!! Actually mean anything?
My mother-tongue is Cantonese. As far as I understand, this is not anything in Cantonese (at least modern Cantonese). Although some of the words sound like Cantonese, for example “Lock shat” sounds like 落實 (lok6 sat9), I can’t think of any meaningful content when they are put together with the words after that.
