Sneak dissing is to make fun of, diss, or
roast someone else without telling them, normally in a whisper.
For example, if you are whispering to your friend about someone else that is right there and he doesn'
t hear it, it's sneak dissing. However, if you say it loud enough but he is too
busy in something else, it isn'
t considered sneak dissing. Commonly referred to as snake dissing by wiggas.
