Twisturbation 

Posting something on Twitter in an effort (conscious or otherwise) to stroke one's own ego, i.e. what nearly every single Twitter user is doing nearly every single time they post something on Twitter. The post itself can be of either a positive or negative nature; the only aspect of import is its lack of useful content, much like actual masturbation.

If you glance, even once, at Snooki's Twitter feed, you have enabled a Twisturbation addict.

Kanye West routinely engages in Twisturbation, showering the masses with his nonsense.
