A disease in which someone acts like a bitch for an extended amount of time. This disease is contagious.
by Kirkland Water December 12, 2010

A serious disease that everyone catches now and again. An individual who has contracted Bitchinitis is generally unwilling to perform an action and often times makes excuses about why he/she cannot do something. The list of excuses can go on and on, but at the core, their lack of apathy is what results in nothing getting done. This disease is very contagious, spreading like wildfire to neighboring persons. Some individuals seem to be more susceptible to Bitchinitis than others, with the intensity and duration varying from person to person.
Person A: "Hey man, do you want to go for a run later on?"
Person B: "Nah. I don't really feel like going for a run. It's so hot out and I'm really tired. Plus, all of my clothes are dirty and I think I sprained my arm yesterday. I just know that it's not going to workout."
Person A: "Are you sure about all those things? To me you just sound like you have a case of Bitchinitis."

Origins date back to at least the very early 60's. Great, the best, hot, excellent, awesome, unbelievably good. In the 60's and 70's was often combined with the word "ass", as in "bitchin-ass", to describe the ultimate, supreme, primo, or a great looking sexy girl.
1. Check out that bitchin car!
2. We had such a bitchin time at the concert.
3. Wow what a bitchin-ass babe!
