I heard "Se quiboca." What does it mean?
"Se quiboca"
That's how you would spell it when you pronounce it, I think?

My guess is that you were hearing the verb: equivocarse = to make a mistake
This is a reflexive verb.
Se equivoca = you (singular formal)/her/him/it/they/you (plural formal) are mistaken or you/etc. are wrong
This is only a guess, maybe someone else has a better idea.
Se equivoca -> You are wrong. She / He / It / is wrong.
