Also known as: 手形, 掌印
The result of when a character's flesh is slapped on by someone else, which is visible reddening. Sometimes a hand print is left behind, and swollen skin can occur as well. Slap marks most commonly happen when the cheek or Ass is slapped. The cheek is often slapped to knock someone back to their senses, while the ass is slapped to punish someone (often in a sexual way i.e. as part of BDSM).
