Missouri Scholars Academy. A three week social and educational session at Mizzou for 330 juniors every July. Commonly noted as "the best three weeks of your life." MSA Alumni signal each other with the call and response of "BOOMBA!" and "HEY!"

Many people who can't get in to MSA call it summer school or nerd camp, but they don't know what they're missing.
Man, MSA was so much better than the real life. Go nerd camp!
