Used anytime someone gets hit in the face with anything: pies, punches, what have you. If it's cum, use facial.
Pixiv has a tag named ジャイアンパンチ (Gian's punch) that came from an episode of Doraemon. It is equivalent to danbooru's face punch tag.
The following tags implicate this tag: pie_in_face and face_punch (learn more).
