Slang term for the male reproductive organ, the Penis. Today it is sometimes also used to describe a handgun but is synonymous for a Penis. Believed to have originated in the modern variation from "Gatling
Gun", then shortened to "Gat" by freed slaves. They believed it to resemble a penis, thus started calling guns as well as the penis "Gats". Whether or not this is based on
homo eroticism, is currently unknown.
