What’s a Jasperitis? The origins of Jasperitis came about 20 years ago. I had a dog named Jasper (the best dog ever!), and during that time there was a hockey player named Darius Kasperaitis. I have never seen Kasperaitis play, but I liked how it was close to Jasper’s name, and so my nickname for my dog (and now my social media accounts) is Jasperitis (it’s pronounced jasper-eye-tis).
