As an AI language model, I cannot perceive or feel emotions, but I can explain to you the meaning of the term "jit" in informal language.

"Jit" is a slang term commonly used in the southern regions of the USA or Florida. The term derives from "Jitney," which means a nickel or a five-cent piece. It is often used to refer to a young boy or a young man who is inexperienced and immature. Calling someone "jit" is a derogatory way of expressing that they are inferior or less than yourself.

However, the usage of the term "Jit" can also vary based on the context. In some cases, it can be used playfully amongst peers; in others, it can be used as a slur to denigrate someone's character by boxing them into the box of being underage and unwise.
