How malleable is meaning? Example: can we take a word that is commonly

How malleable is meaning? Example: can we take a word that is commonly understood to mean/refer to a specific thing and give it an entirely new meaning (or at least one that, despite its slight similarity is still significantly removed from the original)? Example: referring to a traffic light as 'autistic' (given that it operates in one way, without change) without meaning this metaphorically.
