So, these two guys decided they would go get drunk. On their eighth or so tankard, one turns to the other and says "We should make up a language to confuse those in the future". So with their seven "declensions" and 5 "cases" and an infinite amount of irregular verbs, they created the truly confusing language of latin (standing for "Lo! All Total Insane Nonsense") that did indeed confuse those stupid enough to take it as an elective in high school. The end.
I actually have no idea what this is for...questions? Lessons? Something? It's all part of an inside joke that went out of control.
