A communication option on Facebook that allows users to say hello to or show interest in a friend without having to go through the tedious process of crafting coherent sentences in order to express one's self.

The Facebook poke is especially useful in the process of overanalyzing a potential romantic interest's feelings about you based solely on impersonal online interactions.
Stan: I Facebook poked Wendy two hours ago, but she hasn't poked me back yet!

Kyle: That sucks - I guess you're going to have to find a different prom date.

A friendly way of "annoying" someone and reminding them that they have you as a friend on Facebook. Does NOT always mean you're flirting. Can also be something you do in order to keep yourself busy when you're bored.,

A Facebook Poke has been known to lead to a "Poke War" in which two people continue to poke eachother until one stops. The person who stopped poking back lost, thus making the other the winner of the "war"

.. on a personal note, I think Facebook should get a 'dislike button' ., (:

but anyways...POKE!
I poked my friend on Facebook., therefore it is a Facebook poke.

Note: This definition might just appeal to the younger generation >.<

A way of saying "I like you" to someone without actually coming out and saying it to their face. If they poke you back, they are equally interested.
Lisa: I really like this guy, but I don't know what to say to him.
Michele: Facebook poke him.
