Using the social media site Facebook to vent and complain in status updates. Furthermore, a faceplainter is someone who regularly posts faceplaints, annoying their friends almost daily with negative, trivial personal problems.
My "friend" complained yet again on facebook today. Her faceplaint post read: "I have such a headache and have to work until 3, wish I could go home and nap but I have to take the dog for a walk and then make myself dinner because my roomate can't cook and then I'll take a cold shower because the neighbor uses all the hot water and my hair will be fizzy just like it was today. Urg - I hate Monday to Saturday".
