Seaweed Brain

A special title, and there are two most important uses of the title:

1. If your girlfriend is calling you this, smile or laugh and call her Wise Girl. She would love it, and love you more.

2. If anyone else calls you that, feel free to call him/ her any names you want, though it's best to call them "Pinecone face".

Gf: "Hey Seaweed Brain!"
Me: *smiles* "Hey Wise Girl!"

Random Guy: "Yo Seaweed Brain!"
Me: "Don't ever, EVER, call me that again, Pinecone Face!"
