Say we're talking about someone's leg. If we use words like "muscles" and "flesh" to refer to their leg, then that's different than using the words "steak" or "meat", because those last two words are used to legitimize eating the leg in question.

If a friend of yours referred to your skin as "bacon", perhaps you'd laugh because it's an absurd idea that your friend would want to fry and eat your skin for breakfast. But sometimes we use the word "bacon" for real about eating someone's skin, mostly if they're a pig. Those, who don't view it as ethical to commit violence towards others and then eat their bodies, would therefore avoid talking about the skin of others as "bacon" and their muscles as "meat" (unless they were joking, perhaps).

I wouldn't consider "egg" is an oppressive word as such, because it doesn't imply eating per-se. Vegans would still say that a chicken is laying eggs. But "fishing", even though it's just the noun "fish" turned into a verb, is violent because it means "to hunt fish, often for eating". Imagine if the verb "dogging" was used for hunting and killing dogs? "Childing"? "Womaning"?

Sometimes this carnistic language bias is hidden for us. If you're more curious, please check out Melanie Joy's video, The Secret Reason We Eat Meat: https://www.youtube.com/watch?v=ao2GL3NAWQU
