Get good, play reasonably often, then people will start saying things like:

"Hooray, Boyl's here, multiboxing FTW"
"Dude, you've obviously never 5-capped in <8 min because Boylston's here"
"Hey Boylston, where do you want me this game?"
etc etc

I don't ever have to defend myself anymore, usually someone else from the BG steps in and does it for me.
