A person that feels the need to point out that Photoshop was used on an image, no matter how super cool or hilarious the results may be. The fact that people ALREADY KNOW that the image is OBVIOUSLY Photoshopped does not discourage them one bit. They think this makes them seem smart or computer savvy.
"Dude, no way is that rooster THAT big, it's Photoshopped...!" "No REALLY, seven foot roosters aren't real...? I had NO idea, quit being such a Photoshop Tattletale, you're spoiling our fun..."
