guy 1: "Ah, that laptop effect is killing the conversation, just stop!"
To write a Facebook post about a Facebook message/status/event. Is of higher level because written on one's wall (in opposition to in a status' comments).
guy's status: (funny comment)
girl's post on the guy's wall: Dude, your status is hilarious! It sooo deserves metaFacebooking!
