What's the difference between blackmail, deception, deception, calculation and teasing?

Blackmail, deception, deception, calculation and teasing are all synonyms.

Blackmail: written language. It means cheating.

Deception: spoken language. Hide the truth or some behavior so that others don't know the truth.

Fudge: a popular oral expression recently, which is the same as cheating and teasing or mantra. It is a popular fashion term, which will change or disappear over time. For example, people used to like to say "wow", but now few people say it.

Calculation: the tone should be heavier. It is a neutral word, which can mean both positive and negative. If he is a real person, he can live and count. It means praise and careful calculation. You should be careful not to be framed. It means derogatory, used and cheated.

Tease: It means to make fun of others and play tricks on others. It was a deliberate act. Deception is not necessarily intentional, and sometimes it is difficult.

That's all. I wonder if I can help you distinguish these words.
