Don't touch it with a ten foot pole.

This is just a saying that means you don't want to go anywhere a certain, place, person, thing, or situation. For example, "I wouldn't touch a shark with a ten foot pole." This means that you want absolutely nothing to do with sharks, not even be in the same area as a shark. It can also refer to a situation: "Lisa and Rick are fighting again. Man, I wouldn't touch that with a ten foot pole." You just really want to stay away from their drama.
