Who has the most poisonous tongue in the twelve constellations?

Many people will say Scorpio because scorpions are poisonous.

In fact, this is not the case.

Scorpio has the highest EQ, and they will consider other people's feelings, so they won't say those ugly words easily (if you annoy them, that's another matter, they have high EQ, and of course they know how to say that others are the most unhappy).

Personally, Aquarius and Pisces are poisonous, and Gemini is a little bit.

Aquarius is cold-blooded and talented. It is easy to say that others have no right to talk back.

Pisces is too emotional. Without thinking about it, it hurts to steal it.

Gemini and Aquarius have the same reason, but they pay great attention to their words, so their mouths are not very poisonous.

The other constellations seem to be all right.

I don't know if I'm satisfied or not.
