a phenomenon in which electrons are emitted from matter (metals and non-metallic solids, liquids or gases) as a consequence of their absorption of energy from electromagnetic radiation of very short wavelength, such as visible or ultraviolet light. Electrons emitted in this manner may be referred to as "photoelectrons".

"bitchin" is an idiomatic expression originally from the left coast of the United States of America, circa mid to late 1970s, coinciding with the rise of Disco(the Bee Gees), and the "BITCH" fashion trend (where young "woman's libbers" commonly wore necklaces and shirts emblazoned with "BITCH"), used originally by "surfer types", deriving from "man that wave is a bitch" to "what a ride, that wave was bitchin'". It quickly spread to main stream American vernacular as an affermation.

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."
