What Does it Mean To Poke Someone on Facebook? Its a button that allows you to send a sort of digital wave to someone else on facebook. That is it.
But apparently you can be arrested for it in certain situations.
For example, Mrs. Shannon D. Jackson violated a legal order of protection that had been filed against her when she sent a facebook poke to the person under legal protection. I am not sure if she thought this would be a funny joke or what, but whatever the case, she probably wasn’t laughing when she was sent to arrested. So if you are ever in Hendersonville, Tennessee with a legal order of protection you may want to reconsider poking anyone lest you end up getting poke in jail for merely picking up dropped soap.
