What does 고무 mean? Can it mean something other than rubber?
So it was in a video. During a dinner the person receives a steak and says "나는 고무야", they haven't tasted it yet, so it's not like it tastes like rubber. Could it have another meaning when talking about meat/steak? Or maybe there is another word that sounds like 고무 that makes sense in this context?
Thank you.

Question

Answer

If the meat is too tough to chew, we compare it to rubber.

Even if nobody was actually eating in the scene you saw, didn't they try to cut the steak with knives?

Answer

나는 고무야 or 내껀(내것은) 고무야 can mean 'Mine is like rubber.' in that context.
