An almost indescribable sight to see. It is when a man's penis has been inactive and unused for quite some time and then he gets an erection in which the end result is the man's erection looks like a very, very angry panda. This sight is due to the fact that the penis has been so long out of the "game" that it has grown angry and has grown lots of hair with some discoloration due to a feeling of old age. To prevent always show attention to your penis, it has feelings too.
Whoa man put that huge raging panda away, nobody wants to see that.
