Wouldn’t touch it with a bargepole is an expressionindicating extreme dislike and distaste for an object, person or situation. The expression can be used in a similar way to wouldn’t touch her with a 10 foot pole, but is not solely applicable to females; it is even more disparaging when used about a female as it treats her as something less than human.
