Exclusive: Di Kampus Mode Ukhti Kalo Di Ranjang Binal Malay Cino

"Kalo di ranjang binal" – "ranjang" means bed, "binal" is a term for someone who is immoral or behaves badly, and "kalo" is like "if" or "when." So maybe this part is suggesting that if they're on the bed, they're becoming bad or immoral. It's a bit of a double entendre or a judgment towards female students who might be engaging in premarital sex.
