Unsure if this is the right place, but here we are. I need a word that means what I feel like chortle should mean, like a snorty kind of pfft, back of the throat mocking laughter.
This is on the right track, but I need it to be more dismissive. Perhaps it should just be a snort...
I like the use of the word sneer. It's packed with negative undertones and I always think of it as being quite dismissive
