When someone is very open about their heavy drug use as if it's no big deal. Weed doesn't count since it's a pretty mild drug. We're talking heroin, cocaine, meth, ect. They'll post about it on twitter and facebook to act cool. When in reality, they look like attention whores.
FB status: Just got released from the hospital from doing too much coke!! No more drugs for a little while.
Me: Yup, public drug addict.
FB status 2: Im gonna get fucked up on speed this weekend, hell yeah.
Me: Seriously?! Not another public drug addict. *unfriends*
