A place or site, formerly enjoyable to visit, but has become completely obnoxious due to being filled with nothing but excessive and often barely-literate political whining.
I hate going on to Facebook, Twitter, or even Instagram anymore. It's Whiningtime Station all over. It's thoroughly annoying to hear people do nothing but complain. Hard to even find a joke or a cat picture anymore, just whine, whine, whine. Even Urbandictionary has turned in to Whiningtime Station, if you can believe that.
