Wikimongering 

the annoying habit that some people have of allowing wikipedia to permeate every facet of their life to the extent that they must draw a connection to wikipedia in every possible situation, appropriate or not.

<Toothpaste> You should check Wikipedia for that, it has great make-up tips.

Toothpaste is always wikimongering.
