Sarah Lefton designed a T-shirt saying "Yo Semite" after spending time working at a Jewish camp near Yosemite National Park. What does it mean?

In the context of a Jewish summer camp near Yosemite, it's silly, something like the "Shalom Y'all" T-shirts sold by Jewish groups in New Orleans. The National Museum of American Jewish History has been selling this T-shirt design in their gift shop since 2011, with modest sales until the President of the United States managed to thoroughly bungle the pronunciation of Yosemite.
