Question: is sksksksk a bad word?
Answer: "Sksksksk" is a phrase that's mostly typed, sort of like mashing your keyboard as an exclamation. It can stand in for laughter, or express awkwardness, or be the same as an "OMG." It's sort of like saying "I can't even" if it were still 2013. As far as keyboard mashes go, it's a good one.
