What does Yo Semite refer to?

Answer 1

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? Well, it's sort of like wearing a T-shirt that says "Hey Jew" except that the word Semite technically also includes Arabs. 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. That launched a huge surge in sales of this shirt design.
