One of my favorite sites is the Urban Dictionary, http://www.urbandictionary.com You can invent words and add them to the dictionary.
Too many of the entries are juvenile and vulgar but there are a few gems. A few of my favorites:
one who uses their foot to lift the toilet seat or flush a toilet in a public bathroom, as in
“Public bathrooms need to be designed to accomodate the growing tide of sanipeds.” (This is one of mine)
the act of giving oneself a chiropractic adjustment
“it looked like yoga, but he was actually engaging in chirobation” (tips to Jimmy Gaudet)
The feeling of regretting something you’re about to do anyway.
“Every Friday night, I pregret that I will go to the club. I know I will stand there like an idiot and won’t talk enough game to bring anyone home with me.”
