Definition:Gross

Definition
A gross is another name for a set whose cardinality is $12 \times 12$, or $144$.

Linguistic note
The word gross is also an adjective in contemporary American slang for something which is distasteful.

This arises from the fact that a gross is conventionally viewed as a large number, when applied to a quantity of an everyday commodity.

Hence the adverb grossly evolved, which was applied to intensify adjectives, and evolved further to qualify adjectives defining unpleasant qualities.
