Okay, so in the last episode of backstage,"We". In one scene kit says, "Why so glum chum?" And in french Canadian chum means boyfriend. The keaton student's are canadian soooo.....yeah it can possibly be used in that way. And the writers probably used that term as a hint that kax can happen. I found it on Urban Dictionary. It's bascally a slang word. It's mostly used in Quebec Canada.
