(1) Slick dissing is to verbally attack someone in a subliminal way.
(2) It's a way to communicate a message without directly addressing them (not putting their names out).
(3) Mostly done on social media sites.
P. S.: When it happens, people that know both of them knows exactly who the slick diss is referred to and have two tabs open and seat with popcorn to see how it's going to ends up. That's why we are obsess with celebrities Twitter Wars!

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.
