The photo of a man's cock, typically taken by a cell phone, that makes it appear larger than what it really is because there is nothing else in the photo as a frame of reference to indicate it's true size. This is typically a close up zoom of the actual member.
Girl 1: OMG! Your boyfriend's cock is huge!
Girl 2: No, that photo he texted me is just a cocktical illusion. If his hand were in the photo then you'd see that his jimmy is just normal size.
