Webtrovert
Someone who is a shy introvert in real life, but turns into a full-on extroverted party animal on Internet forums and social sites.
Man, she was on Facebook flirting with everyone and talking about all her wild parties, but when we met in person she just stared at the floor and mumbled everytime I asked her something.
Yeah, sounds like she's kind of a webtrovert.
