Meaning of the word "result" in output when using 'this' as the global object

Question

When executing the following code on Chrome's console, it works as expected:

function printNameWithAdj(adjective) {
    alert(this.name + " is " + adjective);
}

var name = "john";
printNameWithAdj.call(this, "nice");

and it prints "john is nice". But when running it in JSFiddle, it gives "result is nice".

Where does result come from, and what is the reason for the difference between the environments/engines?
