I'm glad you liked it! Like a lot of English words, autourophagia is constructed from Greek roots: "auto" means "self," "uro" means "urine," and "phagia" means "eating" or "consuming." Thanks for sharing your story about your mom and grandma. Autourophagia is not very harmful, but I'm not sure if it does any good, and anyone who is thinking about it really should talk to a doctor first.
