TL;DR

"Too Long; Didn't Read" - a shining example of the sweeping Attention Deficit Disorder pandemic that seems to have embraced our society. Usually said by people who a) have never read a book, b) have no logical retort, c) want an easy laugh, or any combination of the three. Not to be confused with "TMS;DU", meaning "Too Many Syllables; Don't Understand", which is likely how some of you reading this feel about this definition.
