I’m going with the second most popular definition of the word “jit” as defined by Urban Dictionary, what with the first most popular being rather NSFW:
The term jit is originally prison slang. It just means somebody younger than you. However, it is most often used to refer to young thugs/wannabe thugs or other punky kids. For instance, you wouldn’t call your 10-year-old cousin a jit.
And now, how the word is used in actual practice (with substantial NSFW language):
“HAM” as it turns out is Word Of The Day #2.
Children are our future, yo.
