Perfect way to describe modern day episodes of The Simpsons. The series was hilarious and fantastic in the ninties but now is totally unfunny and unwatchable. The show's main writers started being replaced 2001-03 and the series started to show signs of low-to-no quality. The movie in 2007 was the only funny thing done since the show started to die. Now the show can be compared to a sick animal that cannot continue living and needs to be put down.
A common mishearing of Shippensburg, PA since it sounds almost identical. Often used to disparage the town or the university named after it.
Guy: "...and I earned my BA from Shippensburg University in 2003."
Bro: "Don't you mean SHITMANSBURG? Pffft what a joke. I did my studies in the hallowed halls of Millersville University you clown."
