-Asserts the given `string` does not contain `value`.
+Asserts that the given `object` (may be an array, or a function, or anything with keys) does not contain *any* of the provided keys. The optional parameter `comparator` is a function which if given an object and a string key, it should return a boolean detailing whether or not the key exists in the object. By default, a shallow check with `Object.prototype.hasOwnProperty` is performed.
 
 ```js
-expect('hello world').toExclude('goodbye')
-expect('hello world').toNotContain('goodbye')
+expect({ a: 1 }).toExcludeKey('b')
+expect({ a: 1, b: 2 }).toExcludeKeys([ 'c', 'd' ])
