Short for Formaldehyde. Relates to any person who demonstrates firm characteristics as well as the ability to promote formaldehyde while carrying the title "Firmy" with pride. Some may believe that the "Firm" aspect of the title "firmy" relates to multiple body parts that are often well respected when firm; however, many have yet to uncover the true meaning.
Hey Firmy, you're looking really firm today!
