buttermilk facial

Describes the process of farting in someone's face after receiving unprotected anal sex with ejaculation, thus covering the face of the other person with small, white drops of semen.
The same thing happens when opening a carton with buttermilk too close to your face.

After finishing her off from behind, that stupid bitch gave me a buttermilk facial!
