One of my favorite sites is the Urban Dictionary, 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.”
