Genocide (mass-killing) of Jews. The term 'jewnocide' is used mainly when you are talking about how no one cares about genocides of Jews. For example, there was a jewnocide during World War II.
The following is an example of someone showing a serious lack of concern when a jewnocide is brought up in conversation. Try this on a friend. They will probably say the same thing.

Someone: Why are you going to kill a British clown?
You: SEE NO ONE CARES ABOUT THE JEWS!

2: Yeah, but look at them while you can because at skin-thirty I'm committing Jeanocide
