Well here is just a few pick up lines, that are related to pokemon:
-Is that a Sudowoodo in your pocket, or are you just happy to see me?
-When I'm around you, I am like a Geodude, as hard as a rock
-Like an Umbreon, I also evolve at night
-Want my Caterpie to use String Shot on you?
-Those are some nice HOOTHOOTS you got there.
-I wish I was a Seaking, so I could HORN DRILL you.
-My Typhlosion knows Eruption. (bolo9642 will laugh at this)
-You just gave me a Cubone.
