A sympathy comment for really bad videos on youtube. If there's a poorly done video that's been up for a while with no likes and no comments, some people will copy & paste "I love this video, it's so cute and sweet" just to make the video's creator feel better.
Video Maker: "Hey, look, someone finally commented on my video!"
Comment: I love this video, it's so cute and sweet
Friend: "Uh...dude, that video must be really lame..."
