Acronym; CFS24-7, which stands for "Creepy Facebook Stalking Twenty-Four/Seven", is a strain of disease one can contract when they spend far too much time on Facebook, and usually takes hold late at night or during procrastination. It causes one to look at anything that pops up in his/her feed, and possibly comment on it, making them seem extremely creepy, as they do not know half of the people whom they stalk. It also causes addiction to Facebook and the creepy behavior one can engage in on this social networking site.
