1) This is the button on the popular social media site, Facebook, that serves no other purpose than to draw the attention of the person subjected to poking to the poker.

2) Otherwise known as the "please look at me, realize how hot I am, and fuck me later" button.
1) "Dude, people keep hitting my poke button and I don't understand why!" "Maybe so you remember they're still alive?"

2) "Dude, I really want to hit that, and she probably doesn't even know I'm alive." "Hit the poke button on Facebook. Maybe she'll notice your pics and then you're ready to go!"
