Pokemon Pick Up Lines is a meme that has been around for a while, but in different forms. The goal is to take terms from the video game Pokemon, and transfer them into pickup lines. Like mentioned, this has been around for a while, especially on the internet. They're similar to PokePuns, but also different. There are about four different macros for Pokemon Pickup lines.

Pick Up Lines Galore has a section devoted entirely to Pokemon, which could be an originating point. http://www.pickuplinesgalore.com/pokemon.html

There's also a blog devoted to the subject.
