Originally defined as girls who take infinite pictures of themselves being, the term has now also included girls who broadcast live or vlog on a regular basis (adapting to newer technology.)
Girls, usually of high school age, broadcast themselves in live and recorded video in an attempt to be showered with compliments by online strangers in a chat or comments section with things like "omg you're so hot." This method allows the girl to feed her incredible natural insecurities without having to be face to face with online stalkers.
Common "fishing for compliments" techniques are:
1. Saying things like "I look horrible today"
2. Putting on a ton of eye makeup, yet trying to appear that getting on video was impromptu
3. Making sure that the camera is framed properly so that cleavage is showing
4. Doing the cliche "smiling yet looking off to the side" look
Camwhores have no substance, only looks. Sometimes they will try to appear to have witty insight on sage-like advice about life or current events, but in the end it is all about craving attention and compliments.
The best thing to do when you spot a camwhore online is to not feed it. Doing so will only perpetuate the behavior.
V-Logging Youtube camwhores always make sure cleavage is visible in the thumbnails in order to attract horny men to click on the videos.
