(Fun with stereotypes. Just don't read it.)

James Mcarthy was your average, angsty, acne-ridden teenager insecure about his sexuality. He reads Marx and wears a Che Guevara t-shirt/fedora by day, and masturbates/cries himself to sleep at night, One day he was browsing rule 34 whilst sitting in Starbucks but totally got all sucked into the screen of his Macbook pro which has become a convenient portal to Equestria. Because Apple is such a sub-standard company with shitty products the transformation wasn't complete and he is popped out as a pony-human abomination. Fun ensues.
