Hmm.... maybe. It seems like praying is what we do when we're not in God's physical presence. But if you define prayer simply as communicating, then I guess so. It's just, when I see God face-to-face and experience the physical sensation of sound waves passing between us, it won't feel to me like I'm "praying."
Maybe this is an Un-Christian meme because of the swear word and it's atheistic implications. I think though that it just shows that atheists don't seem to understand Christian's use of IRONY as a weapon against injustice.
The 'concrete jungle' in the above picture looks like a shopping centre the council built in my home town. They built it with the aim of attracting Marks and Spencer (a well-known UK department store) to the town. They didn't come. The place was horrendous and no one liked. Nobody was disappointed when it was finally demolished.
