Plant nerd 

Any person who is more interested in the growing and consuming of weird plants than the opposite sex.

I caught this guy outside my window. I thought he was watching me undress. Turns out he was getting high off my flowers, fucking plant nerd.

plannerd 

noun. A planning nerd.

An urban planner - student or professional - who is heavily involved in following all things planning, city, transportation, development, transit, etc.

The plannerd recited the entire APA Code of Ethics verbatim while prancing for joy in the new sharrows laid down on Main St and Tweeting about the plans for a new UGB in Portland.
