GrandSlam

In baseball, when the batter hits a home run with the bases loaded.

In tennis, one of the four major competitions.

At Mudd, being stupid enough to take E&M, PChem, and BabyStems all at the same time. (BeforeYouWereBorn, the combination also included the full-semester version of DEs, but it's hardly less fearsome now.)
