Usage

What does thingamabob mean? Thingamabob is a very informal word for an object whose name you don’t know, have forgotten, or can’t recall at the moment. It’s often used to refer to gadgets or parts of things that might not even have a commonly known name, as in Before we attach the bracket, we have to insert this thingamabob here. Thingamabob is sometimes used even if you know the name of the thing you’re referring to. It can be used to be dismissive or to downplay the importance or value of an object, such as when someone is admiring it, as in What, these old thingamabobs? I’ve got a whole boxful of ’em. Take as many as you want. Less commonly, it can be spelled as thingumabob or thingumbob.
