Speaking of dillweed I've always wondered why the Ash named her board dillweed. I looked up the name dillweed the other day in the urbandictionary.com

"Popularized by the Beavis and Butt-head TV series dillweed is a derogatory term used to describe irrational behavior and low intellectual capacity usually resulting in some sort of consequence".

"Literally dillweed likens someone to pubic hair dill being slang for penis, think dill pickle, and weed being slang for hair".

I don't know if the Ash had that in mind or maybe she just likes the herb that is dillweed. Sometimes a cigar is just a cigar.
