The word "不瞅不睬" is formed by directly combining two negated verb phrases: "不瞅" meaning "not to look at", and "不睬" meaning "not to pay attention". Each phrase uses the negation "不" before a verb, "瞅" (to glance) and "睬" (to heed), resulting in a compound that literally signifies "not looking and not heeding", collectively conveying the meaning of complete disregard or indifference.
