A heff is a sigh but also comes with more meaning, it is another way of saying I don't care/ most mean words, you can say it under your breath or out loud to someone they most likely might not know but its a good way of saying it to a disliked one.

Mean words/maybegood

1.(of course) I don't care
2. Fine
3.I'm realeved
4. Leave me alone

5. Stop

Boss : " I told you to clean out the cash register! "
