The phrase "I'm on you" means "I'm on you", which is usually used to describe a person who constantly pays attention to or tracks another person's whereabouts, words and deeds. This kind of behavior will make the people who are concerned feel uncomfortable, not free, and even a little scared. In modern social life, this kind of behavior is considered inappropriate, even an invasion of privacy.

Sometimes, "I am on you" can also mean support and encouragement, especially in the arena. When players or teams encounter some setbacks and difficulties, they usually need spiritual support and encouragement. As spectators or fans, we can express our support and encouragement by shouting and cheering loudly, and even cheer with some gifts and slogans. This is another meaning of "I am on you".

In addition, "I'm on you" can also be used to express threats or challenges. For example, when the two teams are playing, the leading scorer may say "I am on you" to the opponent, which means that I have mastered the rhythm of the game, and you must go all out to have a chance to fight back. In business negotiations, "I am on you" is also used to express a tough stance, which means that the other party must agree to his own requirements before the business can be concluded.
