A party, event or gathering known or designed to attract celeb-watchers whose sole desire is to be snapped by the paparazzi in close proximity to their favourite D-lister in the vain hope that their face appears in the corner of a photo in the next edition of Heat magazine.
China White at closing time, Leicester Square on new-release night, the BAFTAs etc. are all examples of facebait events containing the necessary ingredients of: d-list celebs, paparazzi and excitable and hormonally imbalanced fans.
Cryptic posts in facebook that express a vague sentiment but do not provide any details, clearly designed to bait friends to ask follow-up questions.
A facebook wall post that could be considered facebait would be posts like "Today is the day!" or "Ugh, I am over it..." or "Now I know why I should stay home..." or "Hurt and disappointed..."
A casual mention of Facebook slipped into a conversation in the hope that the person you are talking to will link you to their Facebook page. This can either be to find out more about them, see what they look like (when talking online), or simply just to add to your friend tally.
"I've been talking to a girl online who seems realy nice, but I don't know what she looks like. How can I ask her for a picture without seeming sleazy?"
"Why don't you try Facebaiting?"
A female with an attractive face but a rotund body who is typically found on dating sites and only uses photos from the neck up.
Friend 1: Wow, check out this girls profile she's cool and she's hot.
Friend 2: Dude, don't be fooled she's trying to face bait you with her photo. She probably looks like a beached whale in real life.
