Tie-a-pink-ribbon-around-your-dick

adj. An action meant to be directed at a political, social, or economic issue but having only purely symbolic value, often at the expense of time and energy action that could have been put to something consequential. So named because it feels good to do but does no good.

Person #1: Hey, are you gonna wear a safety pin on your hat to the anti-fascism parade to show solidarity with gay Muslim trans women?
Person #2: No, you ducking slacktivist, I'm on my way to an ACLU meeting to volunteer with their voter-registration drive because I prefer to do things that actually make a difference instead of wasting my time on tie-a-pink-ribbon-around-your-dick bullshit.
