This phenomenon is called lexical blending, where words are combined to create new ones, often with unique meanings.
Lexical blending is a natural process that occurs when we try to describe complex ideas or concepts. It's a way our brains create new words by merging existing ones, often resulting in clever and creative expressions. For example, 'smog' is a blend of 'smoke' and 'fog', while 'brunch' combines 'breakfast' and 'lunch'.
