If there's "absolutely positive", then would there be an expression like "absolutely negative" as well?

This is a great question! Actually, the opposite expression is not used. "Positive" is used to confirm someone's position or decision about something. You can consider it as being similar in meaning to "[are you] sure?" "Absolutely positive" means the same thing as "positive," but with more emphasis added. "Absolutely negative" isn't used, because it's not common for people to confirm the negative over the positive. For example, if someone asks if you're "positive" and you want to answer in the negative, you can simply state "no" or "[I'm/it's/etc.] not" instead. Ex: A: Are you positive you want to skip dinner? B: Positive. Ex: A: Absolutely positive this person is the one who stole your phone? B: 100% positive.
