I wonder if it's a regional thing? I've only ever heard it in movies or older TV shows. Where I live people are much more likely to just say "crippled" or describe someone as walking with a limp.

I was confused when I saw Pulp Fiction as a kid because I was like "why is this handicapped guy in a leather suit and what does him being hadicapped have to do with his apparent hobbies" lol. But like I said, never really heard it used in other contexts.
