1. Acting like a complete douchebag in a way only possible on Facebook. This might involve relatively innocuous things like Facebook stalking or being a Facebook whore, or it might be a little more obnoxious, like telling Friend A that you can't go out on Saturday night and then posting tons of pictures from Friend B's party the next morning.

2. The innate quality of Facebook that inspires this sort of behavior.

The phenomenon of having to come out as bisexual to the same person/people repeatedly because they assumed or hoped that your sexuality was a "phase." Refers less to the holiday and more to the 1993 Bill Murray comedy film in which the main character experiences the same day over and over.

When someone posts something on facebook that is meant to get alot of likes, (ie. LMS or tbh ) and nobody likes it.

This almost never happens to popular people.

Posting something on a social network that you wouldn't want some people to see but are able to see.
