The Big 4 refers to the stuck-up snob universities in the Philippines. Imagine the Ivy League but in development. It consists of the University of the Philippines, De La Salle University, THE Ateneo de Manila University, and University of Santo Tomas. Students from these universities are either militant activists or sons of wealthy capitalists.

The 4 most brutal, extreme, and amazing metal bands ever. They include:
Metallica
Megadeth
Slayer
Anthrax
They're either thrash, heavy, or speed metal.
When it comes to The Big 4, there fans go like this:
Metallica fan- Megadeth sucks!
Megadeth fan- Metallica sucks!
Slayer fan- Like Slayer or I'll slay you!
Anthrax fan- Anthrax is cool.
