Seriously, if you even have to ask that question then you are already in a bad position. The fact that you have now gone and created a permanent public record and been given this sort of feedback makes it even worse.
At this point, you would be nuts to use it.
Take my word for it. It comes from experience. I was once sued because we sold 1 copy of a video called "whoreos" and it sucks balls. Trust me, you would rather spend the money on having a carpenter nail your balls to a board with a rusty nail using a broken hammer before wasting it on that type of law suit.
