Maria Kalaw Katigbak, a Filipino historian, was quoted to call the Batangueños the Super-Tagalogs. This is because these group of people belonging to the Tagalog stock is the paramount example of what one can expect from this ethnolinguistic group. And indeed, when you ask someone to overact a Tagalog, they would imitate the Batangueños.
One particular custom in the Batangan culture is the so called Matanda sa Dugo (lit. older by blood) practice wherein one gives respect not because of age but of consanguinity. During the early times, the custom of having very large families are very common. Thus, it may be expected that the someone's uncle could be of the same age, or even younger than himself. In this case, the older one would call the younger one in an honorary title (such as tiyo or simply kuya if they can no longer establish the relationship), not the other way around. This often draws confusion to those from other provinces who are not accustomed to such practices.
Batangueños are very regionalistic. When one learns that a person in the room is also from Batangas, expect them to be together until the end of the event. It is also expected that those in office would favour their fellow Batangueños as long as the rules could allow it. Thus the running joke, the Batangas Mafia came to existence.
They also tend to live in a large extended family. It is but common that a piece of land remains undivided until the family connection becomes to far-off related. Marriages between relatives of the fifth generation is still restrained in the Batangan culture even if Philippine laws allow it.
Batangueños are heavy drinkers. Men, and sometimes women, could spend long hours of drinking sessions as if there would be no more work the next day. This is specially true if you are to visit the far-flung barangays.
