Here's a breakdown of the phrase:
* No: No
* quiero: I want (present tense of "querer")
* verte: to see you (infinitive "ver" conjugated with the pronoun "te", which means "you" in the informal "tú" form)
* ahorita: right now, at this moment (informal, but very common in many Spanish-speaking regions)
The tone of the phrase depends on the context and how it is said. It could be:
* Firm and direct: If you are serious about not wanting to see the person at that moment.
* Gentle and apologetic: If you are politely declining to see them right now.
* Angry or frustrated: If you are upset with the person and don't want to see them.
