The ELMO is an annual math olympiad that happens at MOP. Its initials have stood for many things over time, originating from a backronym originally called the "Experimental Lincoln Math Olympiad". The black MOPpers and returning MOPpers write and organize the test, and lead the teams of competitors, which consist of rookie MOPpers.

Exceedingly Loquacious Math Olympiad The ELSMO is an addition to the ELMO given to the misguided souls who unfortunately pronounce MOP as "MOSP", with an additional "S". The name and appearance of the ELSMO also differ from the corresponding ELMO, typically with rather questionable design choices.
