Allow the ability to mute specific words

It’s a feature I’ve been wanting for a while now. Let’s say for example that someone’s talking about spoilers for Frozen, well, instead of just muting the person and potentially missing out on anything else they might talk about, why not allow us the feature to mute specific words in stead, so if they’re talking about spoilers or use words that you don’t want to see or hear, you won’t have to anymore, since you can mute the word in particular and won’t have to worry about seeing it again? I think it’d be a great addition, personally.
