Describing something of considerable size and weight, often making it difficult to handle or transport.
This can refer to physical objects, but also metaphorically to things like data or information that are large in scope or quantity.
The term implies that something is not only large but also somewhat unwieldy due to its size and shape.
It suggests an element of awkwardness or inconvenience associated with the item's mass and dimensions.
The core of the definition is the challenge presented by the size and weight of the thing in question.
