A term used to describe the religion that many college students follow on a daily morning basis. Lethargism stems from the word lethargic, or drowsy. The willingness to stay in bed and sleep overpowers logical reasoning such as; coming to class on time, finishing a paper, or study for a test. Similar to the illogical behavior of certain religious activists whose points have been dis-proven through the use of science. Lethargism is exercised by a vast majority of people unbeknownst to them.
