Victoria, B.C. slang for double nostril piercings; if you Google it, chances are no results for such things show up, or if it does, it will show up as double snakebites/double spiderbites. (Four piercings located on the lower lip, two to a side.)
Person 1: "Bro, check out that girl's two nose piercings!"
Person 2: "Yeah, I've always thought dragon bites were sick,"
