Hashtaggery

The annoying act of creating and sharing hashtags to show support for a cause instead of actually doing something useful

Dude 1: "From the safety of my sofa and anonymous Twitter account, I support free speech #JeSuisCharlie"
Dude 2: "Man, that kind of hashtaggery really gets my goat!"
