When a male is either masturbating or fornicating until the very verge of climax, he stops fornicating/masturbating to perform a semi-backward roll so his penis is positioned over his face, and proceeds to ejaculate in his own face. This sexual maneuver is often performed with the mouth open, depending on preference.
Girl #1: So last night me and my boyfriend had sex for the first time, and you'd never guess what he did. He just straight up did a wicks all over his face!!
Girl #2: Damn girl, he sounds nasty! Did he have his mouth open?
Girl #1: Hell yeah he did! He even wanted to give me a snowball kiss afterwards!
