facebook sick 

Someone who creates a really sick (cool) profile pic (photoshoped of course), post really sick comments, has thousands of friends that dont' know them but in person is a total loser.

I friended XXXXXX and couldn't wait to meet them in person. I stalked their profile constantly because it was facebook sick. Then, when we met, I realized I liked them better on their profile

Facebook sickie 

Posting a status update on Facebook claiming to be ill in order to avoid or get our of social commitments or engagements. Differs from vagebooking in that it is not done to attract sympathy or attention, but rather to provide an excuse for staying home. May also be done to corroborate a sick day from work or school.

"I really couldn't be bothered going to the party, so I chucked a facebook sickie."
