A bag of chips (thick cut potato fries) that contains and arbitrary number of chips more than a regular bag of chips. The amount of extra chips is at the discretion and generally based on the mood of the person serving as there is no standard measure for a large chip.
'A thing of' is a very Irish way of describing an inanimate object, usually a container or packaging of sorts. Be it down to laziness, or actually not knowing the name of what the object is, this expression has many uses.
This is a very, very common thing amongst Irish people when describing a person, place or thing. Because sometimes we can't articulate how large or small an object is, or the skin tone of an individual or even the heat of a local curry dish - we use this a lot! We basically just say the word twice and the person who gets the info knows exactly what we mean by tone alone.
