The act of facebooking while simultaneously attempting to compose an essay on microsoft word or other such program.
Time allotment tends to be 99% facebook, .5% going to the bathroom when you don't have to, .4% staring blankly at your essay, and .1% making up excuses for not having your essay.
Friend on facebook: Hey d00d what is up? I haven't talked to you in 4 ever! Lawl I just totally got a new pencil sharpener, want to hear about it?
Friend on facebook: You're not just facebookrastinating, are you?
