Despite being a male both Warden Stillwater and Apothecary Lydon call Johnny a girl. While Stillwater's insanity could contribute to him calling Johnny a girl, it is possible that Lydon found Johnny's manner of speaking about Twinkles as one would a "My Little Pony" doll and crying over its death girlish... or blood elves (lack of) masculinity part of a running gag with Blizzard.
Johnny Awesome's dialogue is reminiscent of "Old Spice Guy" Isaiah Mustafa, from a series of Youtube video spots, promoting Old Spice. Most telling are the bits "Now look at yourself. Now quickly look back at me. Yes this horse *is* made of stars," which is a direct parody of one of his video responses.
Johnny Awesome seems also to like The Steam Pools resort, as since you can find him relaxing with a bunch of blood elf female ladies around him.
