Last Day Of Classes. Used by students in away messages and Facebook status updates to denote their sheer enthusiasm at realizing the semester has come to an end. Exponentially more exciting when it is the LDOC of the year or LDOC of school (i.e. the end of high school, college, or professional school). Can also be the name of a large party held on LDOC.

Unambiguously coined by students at Duke University.
