The suffix 'cide' is being applied increasingly, beyond the obvious suicide, patricide and regicide. 'A shoeicide bomber' had explosive footwear, while 'suitorcide' is destroying one's chances with a potential mate, 'liberticide' is the crushing of a freedom and 'innovicide' is restricting new ideas.

The suffix -cide comes from the Latin suffix -cida, which means "to kill". In this word, this suffix is blended with innovation to give the definition above. There are many other "-cide" words in English, including such death industry standards as "suicide", "homicide", and "genocide". Here are a few unusual variations on this theme:

facticide: To kill facts (i.e., distort the truth).
menticide: To kill the mind, as in a brainwashing.
suitorcide: To do something that kills your chances with a potential mate.
tomecide: To kill books, as in a book burning.
liberticide: To reduce or remove freedoms.

Thanks to John K. Mackenzie for suggesting this word.
