" I have known & used the word gimp since childhood. It was used to describe someone who had a slight limp “ He has been left with a bit of a gimp”. "
Interesting. I too have used the word (noun and adjective) since childhood, as self-descriptors, but the usage "he has been left with a bit of a gimp" is new to me - I would be more likely to say "he's a bit of a gimp, has a bit a bit of a limp". I've also been interested to see how strongly the word is associated with US English, since my own NZE-based idiolect is far removed from US English, yet I've been using "gimp" since the 70s.
