It wasn't too long ago the term "Clemsoning" was part of the college football pop culture lexicon. To "pull a Clemson" was to watch the Tigers lose their season in the most imaginably hilarious fashion. It's where the Tigers would elevate the hopes of their fans, only to crush them and then salvage the season in the worst possible method.
It was the 2011 Tigers who opened up undefeated at 8-0 and rose from unranked to #8 in the nation - then inexplicably lost three of their last four to finish 8-4 on the season. Entering the ACC Championship Game at #21, they beat the Virginia Tech Hokies (ranked #5 in the nation) to win the league and advance to the Orange Bowl, where they naturally lost to #23 West Virginia by giving up 70 points.
