A person that does simple things like change their avatar colour or post a status update about a cause instead of actively supporting the cause.
I just turned my twitter avatar green to support haiti, LOL.
OMG feel well sorry for the people in (major disaster/big news story), hope you get better soon xoxo
n. A political activist who has been active in the past, but in the present mostly talks about politics, drinks beer, smokes weed, and has sex with other activists.
After the strike, noose papier became a slacktivist; he needed the break.
Slacktivists are people who participate in tweetstorms (online) or stand outside in the streets and parks (IRL) screaming for change. These people think they can change the world by holding up cardboard signs. Slacktivism has as much chance of changing Wall Street's ways with Occupy and Anonymous signs as professional wrestling fans do of convincing the general public to "Vote -4- The Rock."
These dirty slacktivists are making it harder for me to do my grocery shopping.
Did you hear the government stopped being corrupt because 500 people RT'd some slacktivism tweet by @YourAnonNews?
Someone who spends all their time on Social Networking Sites doing the work of an activist when they should be working.
I hardly have anything to do at work anymore besides being a slacktivist.
