PEOPLE WHO POST PICS OF THEMSELVES FLIPPING OFF THE CAMERA
While cute the first, second and 4,000th time it was done, this tired image needs to be put down. What the person is attempting to say is "Hey! Lookit me! I'm a rebel and I'll never be no good. Fuck the man, lookit how punk I am! I have a baaaad attitude." What the person is actually saying is "I am bereft of any ideas or original thought, so I must resort to the Hollywood Shorthand method of displaying my 'badassness.'"
Stop it. Be yourself. Unless of course, you ARE actually bereft of any ideas or original thought, then by all means, fake it.
