What does the Javascript error: "TypeError: Invalid calling object" mean? -

i've been running across following error on ie11 intermittently , don't understand it's trying telling me.

    typeerror: invalid calling object 

what error mean in general?
calling object?

    object1()                // object1 considered calling object?     object2.property1        // object2 considered calling object?     object3.property2()      // properties 1 , 2? calling objects?     var stuff = new stuff()  // there calling object here?
