• Name: High-five
  • Originator: Glenn Burke of the Los Angeles Dodgers.
  • Origin date: Oct.2, 1977

This has been around for a while. Supposedly, at a Dodgers basketball practice, Burke wanted to give his teammate a "low five" (Dating, supposedly, from WWII), but they aggreed to "go high", because what basketball player wants to jump high, and five low?

There currently is an initiative to make the third thursday of April national high-five day. You can join the petition by commenting below.
