Slacktivist is 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.

“懒惰的社会知识分子”指的是那些在网上换换头像颜色、或者对某个事件发布一条状态更新，而不是用积极行动去支持这件事的人。

例如：

I just turned my twitter avatar green to support Haiti, LOL.

我刚把推特上的头像换成绿色的，支持海地，哈哈。

OMG feel well sorry for the people in (major disaster/big news story), hope you get better soon xoxo

噢天哪，我对(大灾难/重要新闻中的)这些人们感到难过，希望你们赶快好起来，抱抱。
