Good question! This tool is an extension of a NodeJS library named "Sentencer" (https://github.com/snogcel/Sentencer) -- in a nutshell, it takes word lists of Adjectives and Nouns to assemble sentences based on a given template. The wordlists themselves can be customized, the version I'm using now draws from http://www.ashley-bovan.co.uk/words/partsofspeech.html. I agree that there are some weird ones in there so I might go through and trim out some of these in the future. The list I'm using is a little bit bigger than the one included in Sentencer by default. I did this as I found that certain vowel sounds just weren't as widely used in English so I had to "widen the net" in order to get a good level of variance in the generated sentences. It's kind of a catch-22 that leads to words like "apeak" being included :-)
