BAC
"Banging Asian Chicks"

Derived from the term BHC (Banging Hot Chicks). Not to say that the two terms cannot overlap. BAC is a subdivision of BHC. Popularized at universities with a proportionately large number of asian chicks on campus.
Person 1: Yo, you gonna BHC tonight?

Person 2: You know, I got that yellow fever. It will be more of BAC for me tonight.
